As an update, and so you don't think I've forgotten. I am still looking into some of the Rival Ball issues that have been raised in the last couple weeks (lost scores, ranks, bubbles' logins).
Due to the 30,000+ registered members in RB it has been difficult to quickly find where scores/ranks have changed but I'm working on a few utilties to automate the process and should hopefully have some answers next week. If I find evidence that the game has adversley affected people's scores then I'll do what I can to fix it.
Bungie does probably the same thing for their game except they dont do it like there is a first place or 2nd place they do it in levels 1,2,3,4,5,6,7,8,9, 10 up to 50 on a scoring system of wins and losses
