Ok so I did look into it for like 2 hours and i couldn't find any sort of problem with both the bed and the door. I don't really have a concise way to look into it in a Linux machine, so everything I'm judging is based of off both the Mac and Windows versions. Could you maybe restart the demo? (I know that it doesn't have any sort of savepoint so I'm sorry if you have to go through the beginning all over again).
