The number of active users on Special:Statistics is way off. On the 31st of October the active users where 320, but Special:Statistics claimed that they where 2. And today, the number of active users are 631 but Special:Statistics claim that they are 388.
Perhaps Special:Statistics has a different idea of "active" than you do. I don't know how it counts, but I could imagine that it requires activity over a week or so.
Created attachment 11349 [details] Screenshot that shows -1 active users
No, that is not the case. The number comes from counting the users on Special:ActiveUsers. Anyway, this bug just got worse. Now Special:Statistics shows that the active users are -1. Added a screenshot and upped the importance to normal.
It currently seems to be correct. Please reopen or file a new bug if this happens again.
