Issue
Some ground meats (harvestcraft) can't be made in the pulverizer from their meat form. The tofu version of the meat can be made into ground meat though.
The meats that can't be processed are:
Duck, Mutton, Turkey, Venison

Maybe this is just too much of a minor error, but I thought that maybe you should know ;)

Thanks for letting us know, we'll have a look :)
