@infinitig35 , I think that's one of L4D2 mechanisms, like, special infected will target players more often than bots even when bots are closer to them. But I'm not sure about tank & common infected, as tank usually targets the attackers closest to him & survivor who is using minigun. Normally there's "BOT_CMD_ATTACK" bot command that can order common infected to attack certain target including survivor, & it can be set to only target survivor bots, but I'm not sure if this command will also work on special infected & tank.
