Golems spawn and immediately despawn w/ iron farm


I recently switched my server over to PaperMC and built The Iron Titan farm, only to find that the golems are spawning and within a millisecond they despawn. Another odd thing is that the locations they’re spawning are outside of the typical spawn locations…like for example I’ll see them spawn in mid air on the outside of the farm and then immediately despawn. I’ve never seen this before, so I’m assuming it has something to do with Paper. I just wanted to run it by you guys in case there were any suggestions. Thanks!
