So far everyone whose downloaded our set of mods hasn't had any issues and I'm having a hard time finding anyone with the same issue. The mod is working on the server. Pressing H brings up the GUI and everything. But for some reason on just my set, which is the original set of mods everyone else downloaded, hats are not appearing on players, mobs, or myself. Again it is working because I can pull up the GUI and see the hats.
