This seems to happen once my logic circuits cause my mechanical doors to move. I was building doors that would open for 5 seconds and then close for 5 seconds. Before the crash happens the console fills up with some red words, I do not know how to access the console however. This happened while I was using debug mode.
EDIT: The game stopped crashing once I put some gas next to the doors. Seems like it being in a vacuum caused it to crash.
Steps to Reproduce
Load a debug mode game with doors attached to a logic circuit. Wait until the logic circuit makes the door open or close.
This issue has not been confirmed by a developer yet.
