After updating from Meg 3.0.2 to latest(3.1.0) sometimes there is this error triggered in console and after that, all the models are broken(they seem in idle to the player while in fact they are moving). This error was reported from several users. I have noticed that this happen often after these actions: 1 - Spawning model with /meg summon or /mythicmobs mob spawn 2 - After killing a model with /mm m kill or /kill @e 3 - After hitting a model 4 - On Chunk Unloading when mob is set to not despawn

This error never happened to me in meg 3.0.2, I saw that in changelogs of Meg 3.1.0 the HitBox was modified, in fact the error is triggered for the hitbox of the fake entity. Before saying its Pufferfish(which I have always used and never gave a problem with Meg) I have also tried it on Paper and it happens also on Paper.
