some more information (like screenshots of your plugin manager) and a link to the plugins website would really help here.
that said, all pixel movement type of plugins always have problems with event interaction because originally the event interaction is grid-based and the main purpose of pixelmovement is to remove the grid.
So it always depends on what kind of collision check replaced the grid function, and that is why more info on your project is needed.
It makes sense that you try to focus on the squishy mages at the back of the party first, right? If the mage can out-DPS the enemy DPS before the latter can kill the tank in front, the fight becomes boring.
