Not necessarily a bug, but if there is a lot in the bag and you take it off to wash or exercise it wont let you put it back on unless you empty it out.

Had an odd issue with the place feature. When I placed down one of your bags it came up as the basic bag icon and didnt have any mesh and I was unable to pick it up afterwards

doesnt have a world model

and if the bag has too much stuff in it, the weight is too much for you to pick back up because its not reduced until its equipped, PZ limitation
