I played gently Starmade and suddenly when I tried to put a X 25 x Z 25 piece of purple hulls, the piece appear partially with a an big hole in the middle of the piece (around 6-7 blocks missing). Then I tried to hit the UNDO button but nothing happen. I don't know if the game crashed before I try to hit the UNDO or after I hit it but anyway the game stuck and I was force to ALT+F4 and close the server.
I didn't had perceptible lag, so I have no idea which caused that. But all the things I have done during that session are gone, it acted like a reset.
Here the logs :
