The reference to the error in the title is in the Third Part
This is coming out as a ticking entity issue. From what I have gathered, the ticking entity error is in reference to a mob that has been corrupted in some manner. At least that is my understanding, and the only way to resolve that issue is either by removing the mob (killing it, deleting it's info via NTBExplorer, etc), or removing the mod that is responsible for the entity.
Neither of those options I prefer, so I want to understand what this is, and how to prevent or fix it.
Anyone out there lend a hand? Some advice? Some direction? Sharing their experience?
