So I’ve played Halo 1-3 on legendary and am on Halo 4 mission 5 (Reclaimer) and am half way through the mission but each time I try and resume the mission the entire game crashes I’ve searched up how to fix it and some people have recommended deleting the game then re-downloading it but I’m not sure if i’ll loose any of my progress so if any knows if that would work or if I should do something else I’m all ears
You won’t lose any progress as long as you’ve been playing while connected to the internet. Once you delete the game, your local save gets deleted with it. If you have been connected to Live, your save file will be saved in the cloud as well so you’ll have it right back in your hard drive once you load up the game after re-installing. I’d suggest trying other things before you do that though since re-installing takes a while. If that’s not a problem, then that’s a good way to fix it.
