Chunk loading error, client and server crash.

altiris · August 25, 2014

Having a problem with my world, don't know what to do really. Whenever I go near a certain part of my world I get disconnected with "Internal server error". If I join once more, I get the same error and the server now crashes. If I change my players location to say spawn (using NBTEditor) I can join and play fine. Initially in the log files I had something about Flans mod (although I doubt its flans mod but if I can block the mod just for testing that would be great) but now I seem to just get structure errors leading me to believe its a chunk error. I have made a copy of the world and tried to use MCEdit to delete and create new chunks, still same issue. What else there I can do, I do not want to have to restart on a new world. I appreciate any help, thank you!

server.log of the crash about flans (the crash is still from going in a certain area)
