Was playing in a match this afternoon and following an Assault and Battery, R, in the middle of a fight I noticed that I was unable to use my Vault Breaker, Q. This perpetuated through several deaths, usage of Assault and Battery, and multiple ability casts. Not positive what exactly the source of this problem is but it seemed to be immediately after a teamfight that I noticed I was unable to cast my Q again.
This is happening more and more frequently here as well. Four times, in three different games (just tonight) Vi's Vault Breaker (Q) has stopped working for me as well. It's also happened several times in the past few weeks. If I were to guess it, I'd say it's happened maybe 18/19 times total, resulting in multiple loses. A quickfix is to exit the match and then rejoin but that tends to lead to the aforementioned lose but it's a screwed if you do, screwed if you don't situation.
For it's happened in the middle of team fights, in 1v1 skirmishes and even during hit and runs from junglers. Vi has recently joined my most played characters but this bug is really grating on my nerves.
