basically, i've been hopping around, i came back to my respite, and my walls/floors/roofs etc despawned. the colision for it is still there, but since they're not loaded in on my side, my character keeps falling in place. my crafting stations, and chests are all still visible and fully interactable. you can find the screenshot i took here.
an addendum, it also messed up my portal. there was a card in the slot, but i couldn't open or close the portal, i had to slide another card over it. an easy fix, but still probably something to note.
