you need to use the patched version for spongeforge this is a issue with the ae2 mod that the dev knows about but wishes to not fix at this time since he is focousing on adding in new things to play with :D.

you can find this by going into the #sponge room in irc and typing .ae2 or looking up the user stonebound on this site, or a multitude of other ways
