I have a Tekkit server where I have built an awesome castle. Scince my friends can't playe Tekkit I want to convert my tekkit map to a minecraft map. I moved the map from my tekkit saves to my server's save and it worked allright. But when we come to what used to be a tekkit block my server carshes. I have tried restarts, and other crazy things but I can't get this to work. If any one can help me it would be greatly apreciated.
