I am on a Neoforge server using Synitra connector with the mod, Simple Hats (Fabric 1.21.1 version along with Accessories + compat layers of curios and trinkets). I checked the config and mob loot drop was set to true, but there were no hat bags dropping after killing mobs. I tried creative mode just to get some hat bags and some hats from the item list, but when I use them (right click) they just disappear and they don't even drop with Q.
