The hitbox of big monsters will disappear.

ModelEngine 3.1.2 (Premium) MythicMobs 5.1.2 (Premium)

This bug only works on the big monster in the video, I don't understand, because the smaller monsters don't have this problem, I tried to make the hitbox bigger but nothing changes.

Bug: If a player moves too far away from the target in the video, (200 blocks) and comes back, the target loses his hitbox and is immortal

Here is a video that shows how to reproduce this bug

I think that when you go too far away it reokace the hitbox by the the normal monster hitbox, and not the one of the model
