Character "anchor's" to a location and always returns

Mid game my character stopped responding to move commands. The only way to move her was to hold down the left and right mouse buttons at the same time and point in a direction. As soon as these buttons were released, the character began moving back to the the point it stopped in before. I moved her halfway across the map, crossing obstacles and different lanes. Sure enough, she just walked back to the same spot after letting go of the mouse buttons.

The same bug is described here.

This just happened to me in game on Hanamura. Whole team thinks I’m trolling because of this bug and I was probably reported for it. Also I lost ranked points for a game that we probably would have won without this bug. (We almost won even with the bug as i was able to hold right click to move at least somewhat in position with my team).
Looks like a very old bug based on what Im seeing here on forum. No fix?
I have replay if needed.
