1. Still deciding if we want to fix the Spawner issue. Currently it's an unintended feature.
2. I'll blacklist that.
3. Entities have to wait X amount of ticks (I believe it's 140?) before being teleported again. I can put in a check to have that only apply to players.

1(spawner)
I hope that spawner can teleport.
Thank you for answering.

2(crystal cluster) & 3(item)
Ok, i see.

Had this crash again with the will cluster.
