Unusable Checkpoints

Playing through the campaign as a throwback but is ruined by the checkpoints not saving. This happened to mainly on all the halo missions within MCC PC but is by far the worst on Halo 4, playing through the third mission on H4 and got to the end of the mission (fighting through the covenant (as per) to reach the main thing) and die from a grenade smh. But when I respawn (this is not exaggerated) I go to the start of the mission… WTF

Can someone say whether this is just me or is this just a general and if there’s anyway to trigger the checkpoints there?

This is the Halo 5 forums, this would be more appropriate it the MCC PC forums rather than here.

From personal experience, if your checkpoints aren’t saving then you probably didn’t get a checkpoint - might have been a loading zone instead.
Other than that I don’t know what else to say about the issue
