There seems to be a new bug and that is one of where you cant select your units or right click on anything.
Seems to start at the beginning of the match and cant seem to get control of units back or select anything.

Having the same issue myself. I get into a game and then about 40 seconds in, I can’t click on anything. I can use hotkeys to select things but left or right click becomes unresponsive and I have to leave the game.
