I thought clan scores for the month updated each day after cache flush and were based on data for the last 30 days up to the previous 24 Hrs?
Tools >> Clan >> My stats >> 30 day score.
Showing my total as ~72k when yesterday it was showing ~92k
Stats >> User Clan >> Clan MVPs: 1 month
Showing my total as ~95k which is what I would expect to see.
Problem, or is the 30 day data based on weeks instead of days ?
