[ATM10] Draconic Evolution Energy pylon desactivating and the block turned back to glass

Hi,

Recently i had a problem with my DE setup and it just happened again and i'm wondering whether that's normal or not.

So my DE setup works perfectly fine and i store and use the power IN and OUT of it. However it happened that the energy pylon stopped working and their glass turned back to glass, instead of the power ball we usually see. I then have to break the glass and place it again.

WHy is that ? is this somemthing i am not aware of, or a bug ?

When it's normally working

After the \"bug' happens
