Got a bug, Karos wont make the bed despite my having the wood, and the text icon being green when i interact with him, and Scarlett seems to be sleeping both downstairs and in a phantom bed upstairs. 
update, and I DO NOT RECCOMEND PEOPLE DO THIS, THIS IS TROUBLESHOOTING INFO FOR THE DEV:
This was fully soft locked and i did everything else possible in the game, even full cleared melkors a couple times.
I decompiled the save and incremented the quest counters of the people in question (Karos and Scarlett) backwards, then played through their quest lines again. I believe somewhere in there I managed to go through some action chain in game that caused events to play out of order (i think something like checking on ivys room in a morning before having the bed built, or clearing Karos defense too early, but i havent put in the work to reproduce or test that) which made it so he wouldnt make the bed because the game thought he already made the bed.
