[1.1.2643] Mech cluster landing on top of mountain roof

[Wanderer_joins]

So i've had this mech cluster landing on top of overhead mountain tiles. It resulted in the cluster being crushed, leaving only one minislug turret.

I think this has happened to me as well, and now my game run super slow... did you experience the same thing ? I have no idea what to do as I play permadeath and I have no previous backup
