On version 0.199.528, shipyards are a bit broken. They disconnect my client when attempting to undock a ship that has been created and then cause class cast exceptions when attempting to load another design. I also had an error where it stated the design was too large for the shipyard, but it clearly wasn't. I was doing the experiment on the copy of the LvD world on the dev server at sector 2000, 2000, 2000.
Crash to main menu:
You can then repeat the process to reproduce the problem consistently.

Also possibly related. If you enter the design ship (not physical), then bring up the DEL menu and click the "Undock all" button, it will crash you. Upon rejoining, all the docked entities on the design are gone. Unloading the design and reloading it works, but the entities are still undocked.
And furthermore, when docking a ship to the shipyard and manually undocking, also causes a crash to main menu. When rejoining the server, the ship was also gone.
No trace of it.
Thread dump when class cast exception occurs (taken with VisualVM):
I decided to also test on our server, since I have full access to the logs and could submit them here. I thought it might also be useful to have a snapshot from whatever the issue may have been on the version we are currently running.
It seems there was a class cast exception on version 523, which our server is currently on. I'll include this here as well. This copy of the logs also contains a thread dump. However, on this version, there was no crash to main menu when undocking the entity. Unloading and reloading the design DOES yield another class cast exception though.
Class cast exception when creating design from blueprint.
