Completed all requirements and obtained Legend Achievement back in February with screenshots to prove it (later provided to support). Waypoint does not show this. After wiping my Xbox, reinstalling MCC from scratch and sinking game data my game still shows I have completed everything in Legendary even though their records do not. Solution provided by Chimera30 did not fix the problem. Was told “there is nothing we can do for this specific issue”. Solution provided amounts to do it all over again and MAYBE it might fix the problem. Anyone have a different solution?
Since Waypoint didn’t register pretty much any completions for Halo CE or Halo 2, it means you’re going to have to replay the levels that didn’t sync. I’ve seen this issue before, albeit never on the scale you seem to have it, and the only recourse is to replay levels that didn’t get recorded. This happened to me with a couple levels in Halo 2 during my first time running through it on MCC, and I just bit the bullet and replayed the levels. Make sure when playing that you’re connected to the internet. Also, if you have any 0.0x multiplier skulls on, turn those off. I noticed that you have completions recorded for Halo 3 and Halo 4, which just so happen to not have any skulls that disable scoring. Halo CE and Halo 2, however, have skulls like Bandana and Scarab that are essentially “easy mode” skulls that disable some achievements. I see from your Xbox screenshots that you had 5 skulls active on CE and 7 skulls active on Halo 2, so make sure any skulls you use have at least a 1.0x score modifier.
Thank you very much. Your suggestion about the Bandana Skull being the cause appears correct. It appears the zero multiplier skull prevents it being synced if its your first time you played. For others having this problem I provide what I found in other posts and my own limited experimentation.
Conflicting reports about zero multiplier skulls being a problem or not. Some also say go back and do things on easy and that will get the system to sync your previous completions. I had completed all MCC on Co-Op Legendary, with Bandana Skull for CE and Halo 2, and hadn’t played anything Solo. With the help from Chimera30, here is what I have seen.
-Going back and doing a level on Easy does not immediately sync your Legendary completion as some have said. I Soloed a level on Easy, without zero multiplier skulls, and several hours later I noticed my Co-Op Legendary completion for the same level finally appeared to sync. Currently waiting to see if this happens with other levels.
-The system does not appear to record anything done with a zero multiplier skull, regardless of difficulty level. I Soloed a few levels on easy with a zero multiplier skull and it was not recorded. I then soloed the same levels on Easy, without a zero multiplier skull, it is recorded. Then went back and Soloed, on Legendary, with a zero multiplier skull (the Scarab) and it synced the Solo Legendary and the previous Co-Op Legendary just fine (and also got the Commuter Achievement on level Metropolis).
-My thought is you just need something played without a zero multiplier, regardless of difficulty. Once the system has that you can play with any zero multiplier skull and it will sync/show the highest level of difficulty you’ve completed. It would explain the conflicting reports of which skulls are okay and which aren’t.
