When will felforge next open?

[nanoha]

There has been no activity on this mode for two months，The felforge channel in discord has also been deleted. I can't learn about the opening hours of such activities from other channels。
I expect to experience felforge twice a month

i enjoyed this mode as well and am highly disappointing in not letting this mode continue on when tbc came online... its a travesty i was forced to delete my level 60 felforged. after waiting a month for it to activATE.!
