Others seem to have posted this issue before but I have yet to see a fix.
Having a controller plugged in disables keyboard and mouse control entirely in game. Unplugging the controller leaves keyboard and mouse disabled entirely.
This is a massive pain in the dick. I have to restart the game and I'm left waiting as I still (STILL!!!) cannot join friends in progress.
Please fix this issue and then give me some hope that I will be able to join my friends in progress in the future.
