Curio slots are ignored when searching for an item that should be kept on death, in this example I'm using HeartBond

Heartbond allows you to wear a charm in a special slot that can be bound to an ender soul. This allows players to teleport to each other in a vanilla friendly way, requiring them to hang onto a special item allowing them to teleport to each other, With "ender_heart" added to the keep list, it will save ender hearts in the regular inventory, but not the designated curio slot. this makes me a sad, sad man :(

Support for curio, trinkets & Back Slot would be greatly appriciated
