Simulacrum/An Audience with the King issue/bug

Hello, I would like to address 2 issues that I encountered today, one of them I think was a bug and the other Im not sure whether its by design or an oversight.

Today I was running An audience with the King bossfight with my friend, we died on our first attemt, when I tried to respawn there was a counter with "3 more attempts remaining", but the moment we respawned we were blocked from entering any of the portals because we died, even tho the patch saying the bosses should have up to 5 tries (4 for us because we had the difficulty +1), and It was quite frustrating, It would be great if I could get the item back so I dont have to farm for it again, but obviously if that wont be possible I just wanted to see if anyone else had this problem.

Second issue we encountered in Simulacrum, I dont think this is a bug but I still wanted to suggest a change, the issue is that Simulacrum mobs and bosses dont leave corpses, therefore making things like Herald of Frost/Corpse explosion and the like not proc, and as such making majority of the builds (or at least the variants of builds for clearing that make most sense in a wave themed fight) in game useless or very annoying to use in Delirium or Simulacrum, Its obvious that some builds are better for certain things than others, but I dont think that people should be at a huge disadvantage in an endgame mode just because they do not play the game a certain way like casting spells or using minions, and i think it would be a welcome change if Simulacrum enabled using such abilities for clearing, making it more accesible to most builds that use spirit gems for Heralds because they dont have huge aoe built in a single non-corpse relying spell or minions.

Thank you for the time that took to read this and have a nice day ^^
