was wondering if anyone noticed the glitch with open blocks yet, where if you try to empty your levels into a max'd out tank via drain, then right click the tank; then use the levels that you already have on enchanting or the anvil, then afterwards go back and right click the xp tank again, and u'll get back all your levels back that you used. It's really OP and people keep using it on my server. i don't wanna disable drains but they're starting to twist my arm.
