I was playing Vi.
Here is a crude picture of the situation, I'll explain it better. We (Vi and Brand)were escaping blue after stealing it. We turned to kill Gangplank who was trying to get to 1st tier top tower thru the tribush, who we killed when we caught a glimpse of Trundle in the river, who used Pillar of Filth in the location shown in the picture. I was already charging my Vault Breaker due to the previous encounter. When I charged with Vault Breaker into the river to get to Trundle, I seemingly got stuck on the side of the Pillar, and afterwards, I was stuck in the sprite of the Vault Breaker charge. I could still move, but when I tried to clear Purple side wraiths, I found that I could not auto attack, even though I could use Excessive Force, the attack never happened. I tried to find an ememy to use my ult (R ability) on as well, but that would not work either. Reconnecting and Relogging would not fix the problem.
