I as well, only play online solo. Since Devastation came out, every time I quit Ghosts, the level and rank and all stats/progress gets lost and it is like the movie Groundhog's Day. Everyday I wake up and everything I did the day before didn't matter, I am always reset. I have tried playing on a different account even to see if that made a difference. It did not and both accounts suffer from "don't you dare quit ghosts or you'll gain no progress"
