I had a bit of a breakthrough: I added an event that said "Every Tick, For Each enemySprite --> set enemySprite position to enemyBox" and that seems to work for multiple instances.
Now I need to figure out how to get them to not completely match each other's movements...got them walking but when one turns around, they all turn around, resulting in some of them appearing to be moonwalking...
Also, defeating one enemy destroys every sprite instance...this is frustrating.
