Edited Enemy Crashing Game

[Danarogon AP]

Hello. I've recently made an edited deep-sea diver monster entity file where it has a new "socket" attached to it's head bone. I've made this so that the enemy could have an attached entity to it's "face", for example, a mask and walk around with it. At first it seemed to have worked perfectly. However, as soon as the edited monster attacks me, instead of having the sequence of it "eating" the camera, the game simply crashes. This appears to occur even without an attached entity. If it helps, you can download the entity file here: https://sta.sh/01k57d5e0zy5
