🐛 Describe the bug
It seems to affect piglins specifically causing a bit of lag and overloads memory to completely crashing the game when trying to load, from what I gathered from the logs it's a classloading error that crashes the server on a worker thread when a piglin's (NearestItemSensor) ticks.
📋 Steps to reproduce*
- The error only occurs when the player is near a piglin or has piglin's loaded.
✅ Expected behavior
Normal Async behavior.
❌ Actual behavior
Game lags if you go into the nether dimension and crashes
