It's DTB, but I do use Moghunter for the HUD. But this happens say, P1 has characters Harold (slot 1) and Terrie (Slot 3) with P2 having Geroge (slot 2) and Marisa (slot4). During the enemy turn George got paralyzed. P1 starts his turn and does Harold as usually, however upon skipping George's turn, it is at the selecting a target phase with Terrie.
I was able to replicate this two events issue with Yanfly event chase player; if the chaser notices the P1 just as P2 opens a door, the game locks itself. From what I've seen this issue with two events at the same time seems to be extremely precise to get the engine to soft lock but it's still a possibility if two seperate events are activated at exact same precise moments and the engine gets confused.
