Impossible challenges: Where have all the towers gone?

I've completed nearly all the challenges, but some are impossible in Realms Rebuilt:

• Exterminator: No Fae towers appear, even on Ascended maps. I;ve seen multiple complaints about this in the steam community discussions, so I'm sure this isn't just me.

• Favoured: Favours of Endurance are not appearing as a choice. Instead, the available favour cycles constantly between Power and Soaring, and never disappears, making it possible to hold both and refresh them endlessly.

• Apprentice Lumberjack: Because the Abeyance is only a forest realm now, there's no T1 Berlwood or Spelewood to harvest, stalling the entire Lumberjack progression tree. Playing a Trickstar card and mining sandstone rocks gives specialty woods but these are all Tier2 even in the Abeyance.
