No Loot bug (maps/hideout unlock)

While completing a tier 1 hideout (Felled Hideout), there were 5 rare monsters and none of them dropped any loot at all.
I'd previously failed to unlock the hideout at that location due to dying.
I'm not sure if it's intentional to not get any loot from rares while unlocking a hideout, or after failing to unlock one? but it seemed like it wouldn't be.
Other white mobs dropped some minor loot, so loot was dropping in general, just not from the rares.
Attached the map info below.

I entered a hideout just now and died in 1 mili second,then i re-entered using different waystone and killed about 10ish rare mobs which dropped 0 loot but i could loot chests and blues/whites,it might be just a mechanic for hideouts.

just had this happen myself i alt tabbed after entering the map and died in it reopened it for completion nothing drops. im thinking GGG has something in place to prevent players from reopening the map before finishing to abuse the density
