An Aram with 9 bots?! What is happening

So i recently got a friend into league. While he was taking a break, i played an aram on his account. But what has happend there was so incredibly weird; So basically it started when no one in champ'select' wrote anything, and didnt answer trade requests in any way. But i thought okay, maybe theyre just confused new players. But ingame still nobody wrote a single word and til the.minions spawned, they all hugged the towers. Like they stood in one spot, same as the other team under their tower. Then they started moving all at the same time, and attacking the thing closest to them. Srsly Riot, look at the game footage, its the most recent aram game on the Account Rito GuiltyGille They had normal summernames and had lowlevel accounts but they all moved the same way in exactly the same pattern. Like, you notice if you play against an AI or a human player. That was just weird. And they played too good for a low player in hitting all the skillshots perfectly, but they also stood under enemy tower and attacking it, all of them simultanously, not caring for the enemy team killing them or the towershots. Both teams did that over and over again. Only moving in the middle of the lane.

Like i said just watch the game, idk if i can post the replay somewhere or something. But that was srsly weird.
