Expected Behavior

When I kill pigs and cows in the overworld, they should normally die.

Current Behavior

Pigs and cows in the overworld are aggressive, attack me as soon as I get near them. It also displays their mod name as AbyssalCraft in The One Probe. When I kill those pigs and cows in the overworld (seems to happen only on beaches, though I don't know if that affects it or if that's just coincidence), they make ghast noises as I'm hitting them, and when they die they turn into Demon Pigs and Demon Cows.
