Ok, this makes me feel better than I'm not alone. I posted up on the TF2 forum and what a waste that was. Not one reply.
I'm going to disable SM and do some testing tonight and will report back. I just don't think it's an SM problem but I'll know shortly.
Random, I'm with ya dude. I'm having the same issue as all our players want to play Koth maps but I've had to take them out of rotation to keep the server from crashing.
