I am working to narrow down which mod(s) are causing the above stated entry in my fml-client-0.log file and I think I'm almost there. edit: I am thinking its ExtraBiomesXL and a brief test supports that, but I need to spend more time in world to be certain it is, and that it is the only one. /ramble off so elusive
However, I really don't know the severity of this issue or its possible consequences.
If someone could spare the time to educate me I would really appreciate it.
