Power attacks in Terraria Overhaul make the swing animations in this mod freak out and also desync. Making the player lunge first with the attack itself being delayed by around 0.3 seconds or so. This potentially could be fixed if the mod allowed you to have visual effects but disable custom swing animations. Depending on how intertwined the two features are I don't know how difficult they would be to separate. None of the options currently in the configs seemed to accomplish this.
