I tried to update to the latest Bluepower, but when I try to load my previous world, I crash with this every time: http://pastebin.com/pQ2iyERn

That's a weird crash... It seems to be caused by the world converter when trying to move from the old part system to the new one. I had that crash the other day and I thought I fixed it...
I'll take a look at it and see what I can do to fix it. It shouldn't be too hard

Fixed it yesterday and forgot to close the issue xP
