Kindred Passive Timer Bug

As kindred, if you kill your mark while 2 other champions have their per champion cooldown, the third champion will not have a cooldown before you can pick them again. I.E. Get a mark from top and mid in 2 minutes, and then you mark and kill the adc, the adc will not have a timer before you can mark them again. A minor issue usually, it's very hard to pull this off when not against bots.
