Recently i edited three thousand entries (ns 0) via my bot account. Edit was cleaning, removing non existing template, adding category. Before i started the bot there was 4497 entries ({{NUMBEROFARTICLES}}). After finished editing i noticed that special:statistics showing there is now 2611 entries.
How is it possible & where is other (1886) entries?
Another thing i noticed that if i create an entry without adding any category, Entry's counter don't count that entry (It shows same as before).
