I was trying to use the crafter to make a lapotron crystal from IC2, the energy crystal seemed to have a different meta data than what the recipe calls for, I attempted to bypass this with the crafter causing a server crash. I got this crash http://pastebin.com/ctXEuQQc

Can you describe more exactly what you did and which recipe you used exactly? I just tried to reproduce this with my version and I could craft lapotron crystals from IC2 without any issues.

It may have been a problem with my client. Somehow my client couldn't see the output of ic2 recipes leading me to believe the recipes weren't working. However everyone else on my server could see the output just fine. I'll try to reproduce it again today.

I assume this can be closed? If you still have this problem then please reopen with exact steps to reproduce. Thanks
