As the title says, I need keys for the cultist wealth chest near the river however the NPC near Coppergate Market with the key spawns in dead every time.

Hello,

i play on PS4.
upon building the brewery in my settlement I get the pop up that there is a quest (the case of the missing ale.) when I go into the brewery it’s a mess and the quest tells me to “investigate what happened.” I read everything in the brewery and looked around to no progress the quest to no avail. I finally googled a walk through thinking I was missing something and it turns out you’re supposed to speak with Alwin. So I run around looking for him, he’s not inside the brewery where he’s supposed to be. He is literally dead? (Unable to interact with him, he is laying on the ground) outside. I tried reloading my game to BEFORE I built the brewery and I rebuilt it but the same thing happens. I’ve scoured the internet and multiple websites and forums to see if other people have had this issue but it seems like the main issues are misplaced quest markers (which is a problem with this quest in my game as well but that’s something I could work around) and being unable to pick up the keg after dropping it.Please help as I cannot progress with this quest.

I've played the game so far that all I have to do is chase zealots. When I was looking for Hrothgar, I didn't found him for an hour until I found a dead body that was still there. After many Restarts and savegame Loadings is he still death... my Problem is that i cant Prove his death and i wont get the Confimation in the Order
