Don't know if this has been posted:
When you come across a decayed claim and you see some cupboards usually that were obviously in a house at some point, it means they were in a house when the house decayed. Sometimes, when a house has a basement or attic, and 2 cupboards on top of each other when the house decays (one in the attic in the same spot on one on the main floor below) they will overlap on top of each other on the same tile. If you lift one cupboard, it will unveil the hidden one underneath it and usually will have some items people haven't noticed yet.
