I suppose you mean "server is enforcing file consistency for xxxxxx.mdl", right? I know that one... but two things first:

1. afaik, it doesn't have anything to do with bots. It can happen w/ or w/o them.
2. this thread doesn't belong here - maybe "offtopic" ? Anyways, it's not even remotely a Council discussion, and the Agora IS for Council discussions and general suggestions. Sorry, I don't want to flame or anything, just trying to keep things well-organised.

Ok, now to your problem:It would be helpful to know which .mdl file caused the server inconsistency error. Maybe I'm telling old stuff you already know, but there's a kind of lock on the p-models for the UMP45 and the SG550 (p_ump45.mdl and p_sg550.mdl). Normally this lock only appears if you connect computers and play via LAN, or on the internet. If you play on a listenserver (i.e. only 1 computer for everything), you should be able to use custom models for everything. (It's like this with CS 1.5, at least, and I think they didn't change it).
And I remember I had this problem with several custom models I tried (and I tried MANY), mostly with p-models as well. I can only guess, but maybe these were just sloppy compiles. Afaik, you gotta be especially careful with p-models because they use certain hitboxes, and if a millimeter of the gun model sticks out of these hitboxes, it doesn't work...
