Is there anything wrong with this that could be causing the error. When i run the server from the game in retrieval it dosen't do this.
So can anyone help?

We've started to see this error too. It seems like it's being caused by one of two custom maps we're running - MOH Stalingrad or Farm.

I've taken to combining the custom maps we run into a single PK3 file to avoid the dreaded pk3 checksum error. Dunno if this is contributing or not. :dis:
