There's a bug where Quinn's ult will activate but she won't move. I've been playing her for a while now and I noticed that when you activate her ult and click on the minimap for her to go, she'll sometimes stop moving or go and then stop. This also happens when you activate her ult and target an enemy champion in field of vision. This happens to me quite often and I hope it is a bug and not just me playing the game badly. Hope this helps.
I noticed it happening too when I played Nocturne and I think Illaoi? It happened so frequently in a short amount of time I yelled at my monitor. Super frustrating.
Have you tried this on other champions? I was playing a Vs AI match and I could have sworn I gotten the same bug, but I don't think I was Quinn.
I have gotten the same bug on multiple champions, namely akali and nocturne.
I don't know if this is a bug or not but when I activated Quinn's ult and tried to refund an item I just bought [before activating her ult] the shop wouldn't allow me. I didn't leave the respawn platform mind you, and I had enough room in my inventory.
