Updates on this issue.
This is from a reddit post that I posted a whileback:
"I sent an email with several reports of this to the developers this week, and got a response.
They have identified the source of the problem. When the game gets to the point that it is no longer saving, it will never save again because it hits an Xbox save file limit. Now they are trying to figure out why the saves are getting that big and working on a fix for it.
They didn't give any time line on that fix, but it does appear to be something they are actively working on. I suspect when they figure it out, it'll be listed in the patch notes." - gilyco86 reddit
Looks like this is being looked at but will just have to wait. On another note, i just loaded my glitch save to do some achievements and for so.e reason it saved. It would only save once every hour and it was a save from like 2 hours ago; after all that it would only do it sometimes, so odd.
Deves are looking into it, but no further responses. And my error saves now do save, but in odd intervals(sometimes).
