Every time I load the game up, my customization progress will completely reset and put all of my settings back to default. I am playing on the Game Pass version. However I did also play halo 3 on steam, having it on both game pass and steam so I could mod the steam version and keep the game pass version safe for matchmaking. I have since deleted the steam version in an attempt to fix this. If I load up the game on my console, then all of the settings are reverted back to where they were before this bug. However every time I play on pc my customization and challenge progress gets completely wiped. Really annoying.
