Random times while fighting, I have been unable to click my wrist and elbow joints. Once I am unable to, I cant until the entire match is over.

Is there a reason for this?

Happened to me too please fix this

use /click <joint>

try to ungrap the hand, this usually fixs it
if u don't want to ungrap, search by ur mouse around the joint
and when the join flash just click where is the mouse is

I tried that just now. It isn't helping. It isn't both at the same time. In the last match I played, it was only my right wrist that wouldn't work.

For me, I just hover over the joint and use the zxcv keys on my keyboard. Tell me if that works or no.

you can see if your mouse buttons are on one, that may or may not help!
