Oké, I understand the reason why.
Maybe you should start the leaderboard fresh at the first of every month, and make sure everyone knows, by naming it a monthly leaderboard, or something like that.
And maybe it is possible to keep an "alltime scoreboard"
By the way, I do look in on my villages every day (twice) just to make sure my "babies" are healthy and there are doctors and "breeders" and events are happening
