It starts when it starts.
If we had to guess... Thursday or Friday, assuming that someone is reasonably confident that the latest attempt to fix the tick mark bug hasn't broken anything else.
Be warned: FA started on Beta on Friday. The tick mark clearly was NOT fixed as claimed in the Release Notes just after the last FA. Apparently it is illegal to work on the weekend in Germany, so they left us hanging in the wind all weekend.
On Monday the 'fix' broke chat for 2 days.
On Wednesday chat was working but collections didn't always get recognized as completed, and still....
As a player: I collected 5 toolboxes, and guess what, no tick mark to show a badge. So I naturally wondered if new badges were added or old ones changed, or... I hovered on the Badge box and I had a completed bar for Blacksmith badge. So I opened the badge box and then the tick mark appeared. And stayed... until the box was opened again. I tested this with my final badge a Farmers, and the box took 7 to 8 minutes to notice the conditions for a badge had been met on its own. This state of affairs lasted the entire week.
Marindor told us FA would not go to live under these conditions. Our Beta friends game file readers say FA is not returning to Beta, but going straight to live. Hopefully fixed.
Don't hold your breath.
