So after a ton of hours playing a scenario I'm glad to report I lost all of my time because of a year old buggy game.
Game freezes for no reason as usual. Alt- tab out and windows as usual says arma 3 has stopped working. Big surprise there. Close window, game shuts down, re-open game, go to scenarios, and no more resume buttom. Just play button which means, "Thanks for the money, we don't plan on fixing this."
