[Pierre-Marie Baty]

The HPB_bot keeps pressing the IN_ATTACK key (fire key) when it's dead in order to respawn as soon as possible. You might want to set up a timer in the BotThink() function to let this happen only after 3 seconds of death or so.

Or perhaps (especially if there is some sort of spectator mode during this 3 seconds delay) the bot believes it's alive while it's spectating someone else and attempts to take control of that other player, wasting a lot of resources. If so, you might need to adapt the IsAlive() function for your bots to know exactly when they're alive and when not.
