GAMEPLAY Fiddles drain ability range indicators get stuck
I've only noticed this on fiddlesticks, which is what I normally play with.
If you click drain twice very fast on a jungle monster (imagine spamming waiting for cooldown to finish), the ability range circle will remain on screen. You will be unable to left click and do anything, like use pings with the mouse. You have to right click once to get rid of the range indicator. This can be reproduced most of the time.
I think there is also a related bug to this one. Sometimes when I finish a camp or a monster, the first right click I do on the ground will not register, just like in the above case. Only difference is that there is no ability indicators left on screen. So again I have to right click twice to actually start moving. I can't reproduce this consistently though because I'm not sure really how it is happening.
