Happened twice in one day, both times 10ish minutes in the first operation. 


Mouse stops working so you can only move using the keyboard. 


First time quit raged, second time retrieved the use of the mouse by Win-keying out the game (window mode), open Logitech G-hub and switch the profile to the game (which doesnt mean it wasn't as it will switch to desktop/default as soon as you tab away from the game). Might or might be relevant the fact I mapped AIM/HOLD on my G502's button #5 and both times the game froze while I was aiming. 


The second time, i managed to speak with another team mate that also experienced the same thing, also with a Logitech mouse. This also happened to another team mate on my third game (it was their first match since firing up the game as well since they also had to remap all their key bindings) but I have no idea about the brand of their mouse.
