Hello I'm a new user that downloaded this during the Lunar holiday event, its perfect and exactly what I'm looking for.

As far as I remember it was tracking the Lunar event quests during the various zones just fine.

However, over the last week it has been tracking the Midsummer Fires event (which obviously isn't active) and whenever I click off that preference and keep Love is in the Air it is not displaying anything for any holidays. When I enable all holidays it shows Midsummer Fires only again.

Is there any cache to empty or setting I need to enable to track whatever current Holiday event is happening?

Holidays need to be manually activated in the settings. Are you looking at the Holidays section in /att or in the mini list?

This has received a recent update that allows ATT to automatically track currently-active holidays based on the in-game calendar loading its data.

For some reason, Blizzard uses a bunch of different texture values for each individual holiday event, so it will take some time to verify the texture-filter tracking as we progress through the various events. But technically, this functionality now exists. You can untrack all Seasonal content, and it will become enabled when the holiday is actually active (bearing in mind the actual verification we need to do when the actual holidays roll around).
