The bug is still here , we have arround 100 displays fill with text and when we add a new display with some text our fps drop to 8

The original issue wasn't there anymore, although shop interaction (take and put in as owner) were not working properly. Buttons were greyed out when they should not have been, an ownership problem even though I was the owner.
That's fixed now.

Stay on resolved silly bug

Duplicate, merging tasks.

Good find.
With cannons only the 1st block damage number applies. a 1 million damage cannon has 61 penetration blocks, dealing 40 000 damage on the 1st block and in this case also the planet core.
It's fine for beams
It doesn't work at all for missiles and pulse but that's reported here T461

I can't reliably reproduce it anymore, only got it once now and the exact same steps don't trigger the issue again.

Fixed a while ago

Was fixed between releases.

Should be fixed in 0.199.534

Apparently there is no existing task of this issue. It's one of the older shipyard issues most likely going back to its dev builds.
There's some issue with loading/unloading designs where the game still thinks an older design is loaded, thus "overlaps with structure" as it is part of the shipyard.

Merging with duplicate task, alt gr doesn't work properly.

Since all of the docking/station problems are fixed, all station have now 0 mass and dos not get damage by any weapon (the projectiles hit without dmg).

Updated task, stations have 0.0 mass too

ClassCastException and missing planet cores?
Not entirely sure, logs:

I ran .529 for about an hour and a half and couldnt trigger the debug script or lose any docked entities. Updating to .531 now
Again in .531 cannot seem to trigger the bug. I got loads of messages about docked entities from traders guild faction fleets losing their docks and having them moved, but none of them triggered the debug script and my fleet had no such problems

2 could be a result of the core counting as 2m cube. In your example did you add 19 or 20 blocks to reach dimension of 21?

Does replicate mean: you could get the bug to happen again and thus upload the logs again, or does it mean you replicated the situation and the bug did not happen?

Sorry, i mean the server debug script detected something changed and shut itself down. When i went to view the bombers after reloading it all their docked entities are still attached. So i guess the bug didnt happen but the server thought it did?

Could you provide logs of that session where they disappeared? Zip those up so you don't have to upload them individually. (Drag and drop the file into the comment section to upload to phabricator)

-QA Testing-

Can't reproduce so most likely OSX only.

I think an update to the title of this bug is required - it doesnt only affect NPC fleets, but player fleets aswell. Hopefully this will get some traction, as its currently crippling the use of combat fleets, and its even getting mentioned in YouTube videos (https://www.youtube.com/watch?v=UO74wAJxtPc at 2:40) as 'that fleet turret bug' #FleetTurretBug!
