[BUG] Models not being applied/maintained under certain circumstances

Hey there. Using Model Engine 4.0.6.1, Mythic Mobs don't have their models under either of the following situations:

1. The modeled mob is spawned in an unrendered (or perhaps, unloaded?) chunk. (i.e. pre-emptively spawned in the distance in a Mythic Dungeon.)
2. The player respawns.

In both of these situations, the mobs original appearance returns, but otherwise continues to function as expected. No error logs to speak of, console indicates things are running fine.
