I just had yet another heartbreaking moment as I was in a game that was almost 2 hours long and we were just about to win. The last guy in my squad was stuck in the terrain and I went to the menu to select “kill soldier”. Unfortunately, on Xbox, sometimes it ignores what you click on, and instead automatically flips to “leave game”. The same little bit of “are you sure you want to do this” pops up both on both of the options, so I thought I was clicking the right button.
My SUGGESTION, when actually choosing the option to quit the game, require a button to be HELD for a couple of seconds. This way this is less likely to happen.
(Sidenote: I wonder if this same issue accounts for a bit of the deserters, as some seem to leave really late in the game.)
