I had a bug last night that crashed my game.
My lab was built close to the forest and after a while when I tried to Rightclick on it, my game just crashed.
I'm not sure but think that a tree spawned underneath the lab, causing the bug.
edit: Forget the forest stuff, it just happened again, with a research lab nowhere near a tree.
Solution: Load and just remove the lab and build somewhere else.
Thanks for the awesome game by the way !
