Apparently this has been going on for awhile and hasn't really been addressed as of yet but there seems to be an issue with the Mouse (obviously on M&K) interacting with the game in some way. Randomly I'll be playing a game when my mouse suddenly stops working, I'm not able to shoot or aim or anything and all functionality is completely disabled. Only way to fix is to relaunch Destiny, then all of a sudden it's working perfectly until next time it happens (usually days but I've heard people say every single day). If I alt+TAB the mouse is working fine so it's just limited to Destiny. I use a Razer Deathadder V2 mouse. Hoping this gets fixed, a boost so devs could see would be much appreciated!
