Reply To: Losing scores, ratings, etc with customs
First of all, I would move everything related to TU5 on the stick. My setup and the setup I always recommend is having two USB sticks with the very same structure: TU#, cache file, preferences, gamer account(s). On the hard disk you only have the DLC. That way there’s no way cache, preferences and gamer accounts conflict. The fact that the cache for TU5 is on the hard disk may be the issue.
Second of all, remember that every time you rebuild the cache, you lose all your offline scores, which is all scores for customs. So, the motto is: never rebuild your cache.
