For the last week or so over multiple games I havent been able to auto-scroll. I'm using chrome, Ive quit out and rejoined games, I've signed out and signed back in, I borrowed a friends mouse to see if maybe mine was broke still nothing. I've been having to right click move then scroll up and down to play. EDIT: Update- I saw another post in the forum I have also cleared my cache and have no extensions/antivirus things enabled. 2nd edit: I finished reading the other  forum post, you're working on it. Guess I'll download firefox.  ¯\_(ツ)_/¯
