Bump.

Is there still hope for this addon or should I look for good sqlite editor?

player does not want. I think it wants admin)))

Created a plugin that will do it.
Two things to note about this:
1.) This is the worst way to do it, ideally this would be done through MySQL, but I was too lazy to look and see what would need clearing precisely.
2.) You have to supply a clientID, making it fairly useless, but that would be fairly easy to change, unfortunately I need to go cook dinner.

Registers War3_ResetLevels <client>.
