Issue with JEI. Only happens when chisel is added.

I figured you guys have enough code to look through, so that small chunk is enough. I've saved the full log though, if you need it.

This is the problem with logging errors without cleaning up their cause. However, seems like an issue with BC facades.

My bad. I'll go post the issue with them then.
