No, my controller isn't broken in any way. I know of a few other people this has been happening to. We took a break from the game to play other games for a couple months shortly after 2.4 was released. We came back about two months ago and it was one of the first things we noticed. Seeing other people chiming in saying they're experiencing this too, so I'm somewhat positive that isn't a hardware issue. More of a software issue. Some new code not playing nice with older code.
