I was playing Gambit and I decide to invade the other side. I used the fighting lion and all of a sudden my mouse just wont let me look around or shoot. I get teleported back to my side and it still wont work. I could go into menus but I couldn't click anything. I could also alt-tab and use my mouse on other programs. The second time this happened to me I was playing crucible and it just randomly stopped working. I wasn't using the fighting lion. The only fix I could find is restarting my game.
