I made some class icons for TF2 for the 1x1x4 print brick. It shows up in the screen where you can check/uncheck add-ons, but it doesn't show up in game. I have (in the compressed folder) the server.cs, the description.txt, the prints, and the icons. The prints are 256x256, and the icons are 64x64. Do I need to change the name of the folder? I have it as Print_1x1x4_TF2ClassIcons. Any help would be greatly appreciated.
