I think it's time to switch. In CS 1.5, i've used podbot 2.5 and it was good. Caused me little problems (minor problem with weapon behavior that couldn't be changed more than once, you had to completely exit CS and start a new server). CS 1.6 has gone through alot of updates and the developer has disappeared. IvPBot is very unstable, crashing my server for the n-th time already. (Random error in ivpbot.dll in the middle of a game, bots or no bots)
So let's take Pierre-Marie Baty's
et. al advice and switch...

Podbot even supports the shields.
