When I choose save and exit in the middle of the campaign mission, it does not remember which checkpoint i am on when i resume, and this forces me to restart the entire mission. i am really hesitant to play legendary (Because i suck, and it takes a long time for me to finish a mission, sometimes three hours.) When will this be fixed, or, alternatively, how can i remedy this?
This happens to me as well. The only alternative I have found is to save and quit at the beginning of a new mission, if you predict you won’t have time to finish.

Yes. It’s very annoying. I hope they fix this in the next patch. One thing you can do is to just pause the game until next time. But of course, that includes that you don’t play anything else on the Xbox and leave it on. Not a solution, I now. But a workaround á la “Game & watch” kind of.
Quite a while since I needed to save my games like that. 
Are you in a playlist or just regular campaign? Saving mid campaign worked for me, but not a playlist of campaign 
Yeah I’ve noticed that this happens to me in playlists, but when I played through regular campaigns, it worked fine.
I’ve experienced this repeatedly in CE in both coop and solo, no playlist (standard campaign).
It is so annoying to me that I haven’t picked up the campaign since either.
i don’t want to have to play one level at a time but I also don’t want to have to finish a mission in in he middle of or risk losing progress.
This is why it drives me crazy when people are so quick to say “just go an play campaign” or “campaign has no issues.”
The entire game is messed up. You shouldn’t have to have to tiptoe around game bugs. That is not an enjoyable experience in my opinion.
I hope this next content update addresses this properly.
Same
I’m experiencing the same error. Only seeing it in the H2A campaign though.
I’m having the same problem. I am playing halo CE laso playlist and it’s very difficult to pass the truth and reconciliation. It takes me hours to get into the ship and then when I get into the ship I tried saving but I have to replay everything. Also I’ve tried just leaving the system on but it automatically turns off, same as my t.v. then when I turn everything back on the screen is froze. I’ve tried this 3 times. It’s consistent… I wish I could beat this dang mission. Every mission is the only save point and it freaking sucks!
Yeah, they’ve yet to fix this. Of course I understand that they’ve yet to fix anything really and that this issue is just one in a laundry list of issues that they can’t seem to make any progress on.
I play co-op campaign with a friend who is a fellow Halo fan. Getting through the Halo CE campaign the game crashed on is no fewer than 6 time. A lot of those at the end of a mission.
All progress lost of course!
Hey, but bang up job on adding a bunch of achievements, we really needed that.
