I have some sheet metal doors that were skinned as factory doors and when in inventory, /skin shop doesn't recognize them. I'm also having a problem picking up factory doors in my base, even with a salvaged hammer. Getting message you are not authorized to pick this up from chat. Tried using paint can to change to default and still getting message.
I was able to place in workbench and change to different skin and door was recognized that way by the skin shop.
