Here you can see the 'OnKilled' on top.

And here is the one from the bottom.

They seem to be the same? I didn't notice a difference in any of the two.

However, I also found that confusing as "OnKilled" usually refers when the entity gets killed by the 'kill'command, rather than destroyed, or died. So I was using 'OnBreak' stumped why it was doing nothing.
