Vayne condem bug [GAMEPLAY]

I encountered this bug while playing vayne adc one night. The enemy bot lane was an azir nami bot lane. When we both hit lvl 6, I initated the fight by ulting and qing try to condem azir to the wall. As soon as I went to E azir, he ulted. This caused azir not to condem to the wall, but to his own ult. I understand it was fine with me because I got a double kill, but if I was the azir, it would not have been so fun. I just wanted to report it because it seems minor, but this could have a huge outcome in late game teamfights if azir is stunned in mid lane from a very lucky vayne e. Best of luck finding a fix for it.
