Mythicmobs turning into Vanilla mobs.

Summary Having issues of Neutral mobs (cows, pigs, etc) that spawn from mm spawners turning into regular neutral mobs so they stop dropping the mythicmobs loot drops and instead drop regular vanilla drops but they keep their mythicmobs name.

Steps to reproduce

No steps it just happens.

Current behavior

Mythicmobs turn into regular mobs, and they keep their names given by the Mythicmobs.

Proposed fixes

If the issue can't be identified a potential fix would be find any mob that has a Mythicmob name and if they're not a Mythicmob then delete them automatically.
