Okay, so even though i upgraded the Threat System in 4.1b and 5.0 there is something not calculating correctly in battle. The Character's Threat Generation, Equipment, and Buffs are being applied correctly. I'm going to have to take a deeper look into what is causing this.
I am really sorry for the negative experience this has caused.
-Update-
When I implemented Nina's Crescent Phoenix and Lin's Taunt within the new Threat System, I broke how the calculations were being done. Enemies were no longer taking Threat into consideration. The bug would cause them to prioritize Nina, but would also cause it sometimes to randomly attack someone without taking Threat into consideration.
