Actually i have to report another bug, most old design cannot be built like before, some part are not in the good position and it create an explosion when launched.
Some design explode entirely when created (its quite funny by the way!)
But design created with the editor don't have this problem, it seems its only for the old ones.

Do the crashes happen when you first start the game or while playing or loading new maps?

Regarding any unit that doesn't work properly could you please upload it to the workshop and link it here.

Could you also list your PC specs and OS.

My spec:
OS: Ubuntu
Memory: 32Go
CPU: Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz
GPU: Radeon R9 285/380


I happens on the designer: I've taken some screenshot, i can replicate the crash easily by clicking on the bugged part (named "custom module") (that has been downloaded along the design from the workshop).
One screenshot show how the ship appear from me (i redownloaded it to be sure it wasn't modified), it is from the workshop.
Note that the "explosion" also happens with template design (i've tried)
And strangely it doesn't happen with the one i've created... Shall i upload one ?

I just verified something, sometimes but not always (depending on the design maybe?), the design appear correctly in the editor but is still bugged when i build it, and sometimes it appears incorrectly both in game and in editor view.
I've uploaded the images of when it appears correctly in the editor and build incorrectly f rom the in-game point of view just before it finishes.
