The bug that has been causing games to be flagged as cheating is caused by having a negative number of abilities points left on the Customize Race window. There was a bug that was causing the abilities bonuses to double every time you went to that screen, and that's the bug that I fixed. I didn't realize that two of the major races have negative abilities points left without customization: the Arceans and the Korx.
While you are waiting for the fix, if you want to play the Arceans or the Korx in a metaverse game, you should edit their abilities via the Abilities tab so that they don't have negative points left over.
edit: If you want your scores fixed, e-mail your end game saves and player name to [email protected] and I'll fix them as I have time.
