I see that you have made 2 individual system:a system uses to destroy component after an overlapped event, and another one uses to spawn a new box after the old one has been destroyed.
So i was wondering why you don’t combine those two system into a single one? To explain it further, all you need is create a “Spawn actor from class” node right after the "Destroy Component"node?And then choose your box in the "Spawn actor from class"node in order to make a new box appear right after the disapearance of the one you have destroyed.
A bonus guide; if you can, always made event happen in a single system. Don’t divide it into multiple system, as sometimes logic paradox can happens
