Forge version: 1.17.1(whatever version the modpack on)
Twilight Forest version: 4.0.655
Link to crash log: n/a

Steps to reproduce:

1. go to the alpha yeti cave, which will be bugged, then spawn in the alpha yeti.

What I expected to happen: it to be an open cave, with the alpha yeti having free roam to attack the player

What happened instead: the alpha yeti being trapped in icicles mixed with stone hanging from the ceiling all the way to the bottom of the cave
