Found two bugs

First one. If your in team builder and you happen to go look at someones masteries before you pick your own, it will give you the option to pick theirs.

Second one. If you try to cancel match que and it finds one at the same time, it will take you out of the match but also wont let you find another one because "your already in a match". You have you completely exit out of league and I think it leave busters you too.
