This is my last locked achievement. I played through all the co-op missions on at least heroic, as evidenced by the service record screen. My Waypoint profile says the same thing. I’ve been replaying every mission on heroic co-op, hoping it will unlock by just finishing the one mission that didn’t count for some reason. I only have 4 missions left to replay, but my guess right now is that it’s not going to matter.
Does anyone have any idea what I could do to fix it? Maybe it’s possible to delete all my save files and start a fresh campaign, forcing either Waypoint to resync, or the progress bar to start back at 7% after clearing one mission on a clean save.
I appreciate any info any of you might have. Thanks in advance.
