Lush Isle Logbook Arohongui's Hoard only dropping 1-2 currency items after 0.2.1

I saved up a few Lush Isle logbooks to run after the expedition buffs in 0.2.1, and while the logbooks feel much better overall, now Arohongui's Hoard drops literally only 1 or 2 items, with no loot filter hiding anything. I can't be certain, but all of the regular currency chests in logbooks feel like they're dropping MUCH less as well.

Hoping this is a bug and not a stealth nerf, since I didn't see anything in the patch notes indicating that these were changing in any way.
