I just recently opened up a new private server for me and some friends (Going public after I clean it up and add content) and today I added a custom bag. The bag works and everything, I mean it has a display id that works. I can see the bag in the vendor. However, when I buy the bag and it's in my inventory, the icon isn't the id that I set it to. Instead it's a red question mark. In addition, when I place the bag on my bag bar, there is no icon. It's just invisible. How can I fix this? I tried deleting my cache folder, which didn't do anything. I also have this problem with other custom items too.
