When I use it I disconnect. Not as I cast it, rather, while I'm killing using it. The coins/loot will still be there when I log back in, I just get DC'd while trying to use it with ME.
It's done this from lv1-20. It's maxed and I'm still DCing so it's not just a single level glitch.
Also, server's lagging a lot at the moment, I think FoJ might've just killed it.
