Take out all chest items from a previous playthrough if you are updating to the newer version.
As the 10th anniversary draws near... marking a whole decade of my mod. I have decided to return to my old noob project and polish it with a couple changes.
Instead of merely holding 200 encumbrance, it now holds 500. I also improved the chest's positioning, as it was partially sticking into the floor when I had first made this mod.

This simple mod adds a chest to Caius Cosade's house
The chest holds up to 500, has no ownership, and contains a 25 gold gift.
