Just updated ATT for 9.1.5. The number of "things" has dropped by 9000-10000. My percentage has dropped by about 1.2%. The first thing I note is that there is no Holiday sublist in the main list. Zoned into Darkmoon and nothing comes up in the sublist at all.
Can't roll back to earlier versions as it is completely broken. Please fix!!!

Hello!

Do you have holiday tracking enabled? Its in settings second page.

It was on before, must have defaulted off on the new upgrade. Working now thanks :)
