minions randomly switching targets for no reason at all (?)

not sure if this is an actual bug though, but a lot of times, more noticeably on cannon minions, sometimes they just stop attacking a specific minion and start hitting another one for no real reason

it seems like sometimes when a minion is not being attacked, and i attack it, sometimes minions around me stop what they are doing and start attacking the minion that i attacked, causing it to die, making me miss the last hit

i dont know how to repro this, just in playing the game and looking at how minions are targeting other minions
