*raises hand* if you check the image I posted last, the alien shot me through a standard wall and filing cabinets from inside a different cabinet.
I should have a save file if it would help you?

I'll chip in here too, cept I would also like to ask what is going on... did my alien spawn in a filing cabinet?
