Champs just sitting there

I ended up playing a ranked game toady on an alt (was supposed to be taking a break but u know) and 2 rounds in a row, my and ran to the enemy bench and just sat there (the other round 3 of my champs ran up to the guys precious furyhorn and sat by him, like they thought they could attack the furyhorn!!).. They weren't blocked from getting to the remaining enemies.. Clear routes.. Yet they just sat there.. Doing absolutely NOTHING. Fix your shit riot.
