ARAM bots aren't working properly

I have been playing ARAM this week and I've been getting in groups with 2 and 3 bots in each team. Even worse, all they do is run behind our farthest tower and stand there to chill, standing one on top of each other. They seem to be auto-following each other and once the other team gets close enough to them, they zerg and die quickly. Also, if they eventually reach the other team's Nexus, they retreat and don't attack. They only attack minions in this case.

Pleaase, fix this.
