Power Overload adds a transformer item. Inbuilt Lighting will create a light for it (not sure if it should)... but the issue is that the inbuilt light remains when the transformer is mined. Would it be possible/desirable to change this behavior, so that a light is not left behind... or to not add the light to transformers?

Edit: Not sure what changed but I am no longer able to recreate this issue... please ignore.

My guess is the other mod wasn't raising an event for when it was removed and now is. So my mod now knows when the transformer has been removed and this removes the light.
I guess this as I've seen it with other mods.
