Openblocks Tanks are glitched (infinite XP)

[altiris]

There is a glitch I found with blocks that deal with XP from Openblock such as the Openblock Tank and the Openblock XP Drain blocks. Right click on the openblock tank to take back some of your XP (I took 30). Then go and enchant a tool such (I enchanted a diamond pick axe) and then after enchanting step back on the XP Drain block and for some reason your XP will go back to 30 and it will start being put back into the tank. Essentially infinite XP, this needs to be fixed.
