Hello, so im trying to use heads as a currency on my minecraft realm. I am using player heads, these have also be renamed and lore added. They drop correctly from the custom mobs and the tags as well as name and lore match. The problem is that if I leave, go to another area or wait around long enough and decide to kill another custom mob that is exactly the same, the new head will no longer stack with the old one! Also it refuses to be used by the trading villagers who accept these currencys, they do however accept the heads on occasion, normally the fresh ones. The pictures provided show that the items match yet refuse to stack, thank you!
