Thanks, Flitter. It's good to know how UT stats really works, even though it seems broken. I have reinstalled my game a number of times; seems that installing various mods, packages, patches, driver 'upgrades', as well as just uninstalling to free up space when bored w/ game, can lead to the reinstall pattern.
It makes me curious then; how do they know I reinstalled the game? What makes my access 'unique' if it is not some combination of my game serial and player name?
I have noticed new entries come just because I change my name (there is now a Jammu entry). Maybe I'll keep closer tabs on this.
