Describe the bug you're experiencing

My summoned mini-bosses and other helpers etc of a particular boss I'm trying to perfect is having issues. The katana is meant to spawn in their main hand, but it's being immediately overridden by an iron sword.
I have a feeling this is your doing. the same nbt I give it spawns the katana just fine when spawned as a boss directly (the nbt contains brutal boss nbt to give the summon skills and special ai ai also), and also when spawned through a command.

This also likely explains why I get completely obliterated by these chickens in one of my other bosses, because suddenly they all have the stagger and damage power of a free iron sword I can't see:

Reproducability

yes.
it just happens.

make a boss, make it summon nbt'd or otherwise mobs.
summoned mob gets a free sword. Before I was canceling the loot table with an empty table so the summons are less farmable I was SO confused why my inventory was full of mostly broken iron swords mixed in with the chicken feathers and meat of the cucko boss's minions.

Mod up to date

• Before submitting this issue I updated to the newest version and reproduced it

Logs

nothing to log. it's not an error of the datapack but the mod when it spawns these things in.

fixed in 3.3, was a leftover from before summoned mobs could be customized via nbt

alrighty. thank you.
