I recently have been trying to sell "Just Cause 3" on scrap.tf's steam game buyer. However, everytime I've attempted to access the sell menu it has told me that it is unable to load my backpack from steam. I've tried again and again for around 3-4 weeks now and I still have no success. Everything on my profile is public as well. I would appreciate it if an admin could offer some assistance. Here is my steam profile if you need to contact me directly.
