Hello all, in a mod I am working on I made some edits to a small cave.

I added a short new hallway. I capped the hallway with a large stone. I placed a coffin in the hall, and laid an iron sword on top.

In game, the hall is there, the coffin is there, the large stone and iron sword are not. What could cause the game to just.. not show things? Furthermore, while the stone that caps the hallway is not showing up, its collision is there in game..

Thank you.
