House was wrongly flagged for auto-demolition.

[Sotaris]

The help info is wrong, the key word is "use", just entering isn't enough, you have to move an object, use an object, do a thing, interact with a retainer, or otherwise cause the server to notice you exist. It's an intentional trap to make more houses available faster.

GM's won't admit this to you, that's why your in a loop with them.

I'm not so sure that's true. When I've got the warning my house, it has reset by simply entering my house.
