A Mutation overriding an enchantment-given mutation causes a crash

[RobbieNeko]

Describe the bug

When a mutation is provided by a enchantment (attached to a bionic), any attempt to mutate a conflicting mutation type (I.E. SKIN, CLAWS) will crash the game.

Steps To Reproduce

1. Create a bionic that has an "always" enchantment effect that provides a mutation
2. Via mutagens or debugging, attempt to mutate a mutation that conflicts with the first

Reporting this bug on behalf of BaronOhShi in the Discord (they were having issues with their email on github), I have not personally experienced or tested this bug (yet)

[Ignaramico]

same happens when you equip an item with relic data giving a mutation, and you equip another one that cancels it, well i was testing a way to erase spell classes so maybe it had something to do with the spells being erased too
