Two other things:
1. CT bots never try to rescue hostages. They will walk into them, and get annoyed that they are an obstruction to wherever they are trying to go, but the only time they attempt to "use" hostages is if you are leading hostages to the rescue zone, then the bots will come and steal the hostages from you and go wander randomly with them. It's just a little bit ANNOYING AS CRAP!!! Perhaps it is another aspect of the "team goals have a very low priority" problem.>
2. The fence by the sewer entrance in cs_militia is a bot trap now. The bots are magically drawn to it like flies to a manure pile and they all spend the rest of the round trying to walk through it. You need to add the fence entity to the list of things the bots don't try to walk through.
