Some old dungeons no longer give loot

[Bragrak]

Hello

 

Today i just went to try and farm some of the old outfits (mainly Shattered Masts and Ebondrake Citadel) right now those are pretty easy to solo for me, but, when i defeated the last boss there was no loot, not even dumplings, on both bosses.

 

I dont know why, i dont think im killing the bosses to fast (EC has 30m and i am R8 so its not possible there) and i dont see any other way of getting those outfits.
