Summary
Items given/dropped by MythicMobs have an NBT format that is different from the one Minecraft 1.16.X uses, causing issues with stacking after server reloads. It seems that paper is not going to fix this, so action must be taken by every plugin (most plugins already did)
Steps to reproduce
1- Get any item with /mm i get command. 2- Restart the server 3- Get the same item. It should not stack 4 (Optional)- Check the NBT of the items, it should be in a different format.
Current behavior
After server reloads, mob drops don't stack with each other, which makes it annoying for most players.

Intended correct behavior
MythicMobs gives items that are already compatible with 1.16.X format, not needing for a reload to happen for these items to stack.

Proposed fixes
Change the way items are given. Other plugins have already changed the formatting of items given so it's possible. (Essentials has already done this. Giving yourself any item with NBT data will have the new item format
NBT OF ITEM GIVEN WITH ESSENTIALS COMMAND: /I DIAMOND_PICKAXE 1 NAME:&6Super (Here you can see the given item has the new format, unlike MythicMobs which keeps the old NBT format)
