Describe the bug

Setting your Ice and Fire mount seems to occasionally leave them stuck in whatever mode you set them in as the chunks unloaded: Hippogryphs and Amphitheres left in "Stay" mode unable to move even after commanded to follow or wander. Amphitheres still teleport on follow but are unable to fly even when ridden. Hippogryphs can still "fly" but not on their own. Leaves them unable to breed since they're not considered "Wandering." Takes the chunks unloading after the creature has been commanded something else to fix them.

To Reproduce

Tame a hippogryph or Ampithere and set them to stay at whatever location, leave the general area for a while and come back, then set the mount to wander. They'll remain sitting and unable to move about.

Expected behavior

Setting a hippogryph or amphithere to wander allowing them to wander, follow to follow and etc. "Wandering" hippogryphs being breedable instead of just sitting there stuck.

Screenshots

Amphithere Set to follow, head lowered as if in that state but body and wings still stuck in shape, unable to move or fly
