@ Huntakillaz: Right. That's where I wanted to point our new lad. But when I went to your site, it said the traffic limit had been exceeded... that's why I didn't write anything about it.
@ glabb: You can prevent bots from joining automatically by removing a few lines from the file "podbot.cfg" (should be in cstrike\addons\podbot\). Just open it with Notepad (or whatever text file editor you may use) and search for lines that say "addbot". You ought to find a little paragraph that explains a bit about this addbot feature, and right below there should be some "addbot" lines. If you remove them or comment them out (by changing them from "addbot" to "#addbot"), no bot will join automatically. To make 100% sure bots don't join automatically, find the parameter "min_bots", and if the number behind is higher than zero (e.g. min_bots 4"), change it to zero ("min_bots 0").
The other "error" is actually not an error. PODBot 2.5 used to calculate the visibility table for a map every time you started a game on that map. PODBot 2.6mm calculates the visibility table once, saves it as soon as you change to another mao, and the next time you play, it just loads the previously saved visibility table from a file.
This means that PB 2.6mm will create visibility tables once for every map. Unless you change the waypoint files, the visibility table will never be calculated again.
While calculation of the visibility table is in progress, you will see the HUD message you saw, and you will notice that the game runs kinda choppy. After some seconds (the bigger the waypoint file, the longer it takes), the game will behave normally again. The next time you play that map, you won't notice any lag at all, because the visibility table can be quickly loaded from the file that was created the last time.
You can change to your waypoint folder and see the visibility tables. They are called like the map they belong to, and their extension is "pvi". The visibility table for de_dust, for example, would be called "de_dust.pvi".
As for the crash you get on awp_map, I can't come up with anything smart spontaneously, sorry...
