Every event and function claim to be infinite loop

Hey, i was working on a game mode that buils the world as you play and i made some pickup items with different values that add to your score. I wanted to streamline it a bit and made two instances from one pickup item, but then all of a sudden, every destroy actor node, and event ( begin play, actor overlap, etc) claimed to crash due to infinite loop when calling stack. As soon as i try to play, a new item claims the same error. I had no problems prior to making that instance. I have deleted the instance, but everything still complains, as long as that game mode is active.
