Xbox Series X user here, I just tried to download some maps from some file shares to use them for a Doubles retro tourney, just to find out that they are now not playable. The variants just don’t appear in the map selection menu, and if you go to your File/Share and try to upload a file, you would see a “corrupted file” in place of those variants.
They used to work fine since the big migration, now the update screwed things up and they became unusable. In the F/S they look fine, but once you download them, they become corrupted…
343 can’t do a single thing without screwing something, it’s unbelievable,
I’m now wondering if this issue is on Xbox only or also PC users are experiencing it.
I’m on series s and had the same thing happen to a few Halo 3 MLG maps I had (4 in total I think) and the octagon and hardcore 1v1 gamemode I had was also corrupted.
"* Players may see their Halo 3 game and map variants or Halo 3: ODST Firefight game variants appearing as ‘corrupted’ in-game. These variants will not be available for use in Custom Games.
While these files may appear to be corrupted, the issue is not due to the files themselves. A future update for Halo: The Master Chief Collection will restore the game’s ability to read these files correctly.*"
If you’re on PC then you could save the gametype or forge map outside of the game files to free up a private file spot. (Or stash them where the built-in files are to get around the 50 file limit.) For PC players the locally saved files can be found here:
C:\Users\<USER>\AppData\LocalLow\MCC\LocalFiles
They’re sorted first by Halo game and then by gametype or map; .mvar files are forge maps and .bin files are gametypes. Don’t mix up which Halo game they go to. Don’t edit the contents of the file. You can often see the name or description of a file by opening it up in Notepad, turning on Word Wrap, and looking near the top of the file. You can edit the filename but again do not ever edit the contents of the file directly with Notepad.
