Bots stop spawning when playing sabotage?

[theminecraften66]

so when i play play sabotage on any map the bots stop spawning after a few minutes and was wondering if this is a script error or if it is because of punkbuster or something else.

sabotage goes into deathmatch mode where spawns are disabled

um so it happens halfway through the match and seems like one team has two or three stop spawning where as the other team has all but two bots spawning. I play in private match if that helps
