That is a good question. The visible cubes are actually children to the Cube_BP’s parent. So, from a friend’s advice, I made child entities from the base settings. I did, however, think of throwing something more specific in after the parent function is carried out for the metal cubes that are supposed to conduct when touching a starting cube and lose power when not touching.
Regarding the tick, should I remove the nodes after that on the base BP? And yes, the cubes stay powered after touching. (Sorry, I forgot to add that part when I first answered.)
