Pigmen attacking unprovoked.

[Aisu223]

No mining, no attacking, nothing. I kill @e, summon one in the overworld, nether, anywhere, and I get instantly attacked on sight. What the hell is going on and how do i fix this?

Check the configs for nether ores (and any other likely suspects) for an option for permanant aggro.

If not; remove half the mods and reload the game.

If the problem persists then remove half of the remaining
If the problem is fixed, set that half into a separate folder and repeat with the other half.​
