I'm not sure if it's related but I may have discovered a possible cause for issues when building turrets in the shipyard. I downloaded a sment file for a turret which I can spawn from blueprint without issue. In the shipyard however it gave a vague error about being unable to load correctly (sorry I don't have exact message right now). It loaded the base but not the gun portion.

I discovered that if I turned off the BobbyAI and saved the blueprint under a new name I could then use it successfully to create the full turret in the shipyard. So perhaps either the bobby AI being active when a blueprint is saved causes issues or perhaps there's something related to old saved blueprints not loading correctly?

@Hyarion ... add the blueprint that spawns properly here please.

I hit this as well.
Attaching the SMSEC of the shipyard. with the problematic ship already docked

The long sorded story (with pictures!)

1. 
   Docked in the shipyard and ready for work.
2. 
   Deconstructing to Design
3. 
   The ship is nicely displayed in holographic form.
4. 
   Almost Done
5. 
   Rebuilding in progress.
6. 
   Done Rebuilding
7. 
   Re-disassembly
8. 
   Leftovers
9. 
   LEFTOVERS!

Observations:

• Some rail-docked elements remained part of the ship, some dissociated.
• Even between identical docked structures, some worked and some did not.
• On some turrets, both parts became disconnected, on some, just the gun portion.
• The leftovers are not really there physically. They can't be shot or harvested. On reload of the sector they become real, but they are 200-300m from their original position... which at least clears them out of the way.
• If I enter the holographic ship I can still save it as a blueprint through the catalog/blueprint menu. If I admin load that blueprint, that ship spawns in correctly with all attached structures attached and working perfectly.

Docked structures that became disconnected: (varies from try to try)

• 3 turrets (gun and base)
• 3 turrets (gun parts)
• 1 internal elevator (linear rail)
• 1 external elevator (linear rail)

Docked structures that spawned in correctly and remained connected:

• the shuttle (rear of the ship) (linear rail)
• 2 Shuttle bay doors (linear rail)
• 1 internal elevator (Just like the one that failed above) (linear rail) (also failed in previous experiment)
• 1 external elevator (Just like the one that failed above) (linear rail) (also failed in previous experiment)
• 2 Bussard rotors (The spinny things on the warp nacelles (rail rotators, cw and ccw respectively)

I'm having the same issue. I'm having this issue with ships that have been converted from a blueprint to a design.

Ship related.

Can this be bumped up a bit? Kind of breaks shipyards currently.

@Comr4de .. the issue is Urgent ever since validation

I... was looking at a different bug, tabbed out, tabbed back to this. I bring dishonor.

As of v0.19242 I'm still having a ton of problems with the rail docked parts of this ship:

The holographic design created looks to be accurate, and if you create a blueprint from that design the ship doesn't seem to have any issues that I noticed.

When you actually build the ship in a shipyard however, the rail docked landing gear is broken and spawns in the fully extended position. The blueprint and design have it saved in the retracted position. The airlock doors and satellite dish also seem to have issues (sometimes?). Some of the logic related to these parts may be broken as well, but I'm not sure how it all goes together as I didn't create the ship myself.

The most recent attempt to construct the ship tossed out a bunch of nullpointers.

Maybe related issue: The display modules in the ship no longer have data entered after being constructed in a shipyard.

Well ... last night I took a chance and built a ship in the shipyard ... Bad choice on my part.

Ship designed, constructed, used, docked to homebase space station.

Returned to find is had vanished like the turrets I had lost previously. This ship had no turrets, elevators or rails other than the rail docker used to dock to my station.

I ndeed as far as i could determine it affects rails only

I dont know if the orientation of Turret axis, rotator (left right) do get handled in this case individually .. so i would have to check that again to yerify that they are not in fact affected

the rail tranformations of a spawned ship are not adaped. This means a ship will spawn with its rails in the initial position (aligned docker to rail it originally docked to)

what version was that on?

also @SmilingDemon, can you upload the ship where this is happening.

You may use gaeasson sector upload ... the elevators are on top of the disk

i have a test setup i can upload after work

Version .19401

I should add, I added this because it seems that all the focus is on rails and I wanted to make sure the ship issue was also being addressed.

Further detail. Rebuilt lost ship via create blueprint function in shipyard, ship still present this morning. (If that means anything)

Fixed in 0.19421

I'm still having this issue.

Last night, i "printed" 9 identical very small turrets, and 2 large ones in the shipyard in a pretty short amount of time. And docked them all to the same ship.

Upon relogin:
Of the 9 smaller turrets, 4 were missing the top docked weapons and ai, 1 was missing entirely, and one was missing it's base

Of the two larger turrets, one was missing it's base.

This is in ver.19431

When I flew the "top" of the turret whose base disappeared to the shipyard, the shipyard would not register that anything was even docked.

The loss has stayed the same. So what whatever caused the loss is not "spreading".

I cannot discern a reason for which turrets had issues.

This is still an issue in the latest stable version.
I created a fairly big ship in a shipyard, then took it out for a test flight. Only the main ship was in the test sector, together with 1 attached part on a rail. All other rail items connected to this part were missing.
Upon return to the base i notice ghostblock remnants of what were the missing parts. Albeit shifted in place. These ghostblocks can't be intereacted with in any way. When the server is rebooted, these ghostblocks materialize in the center of the planet right below the shipyard. (and causing some collision lag as well)

I'm happy to provide a blueprint or universe download if needed. Or reproduce this issue on the actual server.

Katarone beat me to it. I confirm his report, it's happening again.

Reopening, happens again and has to be looked at again. Possibly influenced by another shipyard related task.

This issues has been reported before, by me, and was merged with another. I was having the same issues. You might find the other missing parts around your sector somewhere.

This looks/sounds a lot like http://phab.starma.de/T834.

WOOHOOO!

Sorry for the useless comment but I am so happy to hear this :D

-QA Testing-

Not fixed.

the two marked cores do not move in the vertical direction.
Undocking and redocking them will make them move normal.

Spawning directly by blueprint works normal:

Blueprint from screenshot.

I think you guys got this one... Been using shipyards for the past two updates with no problems, other than AI turrets not inheriting AI settings.

furthermore, AI settings will now be transferred

Any plans to streamline turret construction in the future?

Unless I've somehow missed a trick, there's no way to attach a ship core without coming out of build mode and it gets tedious.

Personally I've also always thought turret A.I should re enable once a player leaves.

I guess with the right logic systems in place, players can decide for themselves.

If memory serves, the last report I've heard about this bug is that it only happens after a certain number of turrets. Maybe 10 or so? Needs testing with a lot of turrets and preferably a larger ship than typical testing articles. Try a faction-level setup with some big turrets and lots of point-defense.
