So I set up a gold/bartering farm because what I'm building needs crying obsidian and I keep getting these zombied piglins that has way too much heath to be instantly killed, so they will just sit in the kill spot taking up much need spawn cap.
I think it's the Sophisticated Backpacks mod but I tore into it like ten times, disabling everything I can think of (health buff, piglins spawning with backpacks in general, buffs) and I still get them.
I'm on modded 1.21.8 Neoforge and it's a personal pack.
