Sastasha third boss doesn't spawn a loot chest

[Iscah]

I just ran the duty unsynched on my main and can confirm that the loot chest in question didn't show up that second time either. I guess it's permanently removed, but I'm not sure if that is intended?

It's certainly permanently removed since the dungeon loot rework, not just a temporary glitch for you. The question is whether or not it was deliberate.

There are also a number of other oddities - I haven't checked through every dungeon, but two that I've come across are:

Brayflox's Longstop: the Deep Jungle Coeurl in the side area just before the end of the dungeon used to guard a chest containing rings. The rings have now moved elsewhere and the coeurl is guarding nothing.

Lost City of Amdapor: had a pair of treasure chests where one was a real chest and one was a mimic so it was 50/50 luck opening it. Now there's no chest, just the mimic.

The level 50 dungeons seem particularly sparse for chests now - you only get them from the bosses. I would have liked to see more gear added to them rather than just being removed entirely.
