Hi one of the servers I have added to game-tracker is not keeping track of player stats such as playtime and score. it's located here, I have tried deleting it and re-adding it to game-tracker but it didn't work. does anyone have a solution?

Do your players ever have a score? I've been monitoring for a little while and do not see any. GT will not have any scores to track if your players never have any.

yes they do get scores and it was tracking fine for a bit then stopped

You'll need to do a bit of testing and play around with it to get it working again. Perhaps you installed a mod recently that is causing scores to be returned as all 0s in the query.
