I made an Experience Rotor from Enchantment Industry to convert some form of Liquid Experience to the one Enchantment Industry itself uses, since the others couldn't be pumped into the Printer.

The moment I dropped the rotor into the Mixer's Basin, the server crashed. And again every time I log in.

Happened on Version .20, still happens on .21 though.

It might actually not be the rotor itself, but have something to do with enchantment industry's liquid experience in combination with the printer.

I just ran into another crash, again trying to make liquid experience so I can use this darn printer. This time, instead of using the rotor, I tried to simply drain some bottles o' enchanting. Instantly crashed as the first bottle hit the drain.

I tried to recreate this in Creative:

I put down a drain, attached a hopper to it, put a bottle o 'enchanting into the hopper. bottle hopped over the drain, and got emptied just fine, all as it should. I added a tank and connected tank and drain via a pipez fluid pipe. liquid entered the tank just fine. I replaced the tank with a printer - instant crash the moment the liquid experience entered the printer.
