Tables and chairs replaced by sidewalk

Happening in the lastest experimental build. Curses if it’s any different.

Thanks for the bug report, it’s now been submitted to our bug tracker!

Where exactly?

I first noticed it in a mansion, on those very long tables. At first I tought it was something new, maybe a running strip or something. But then I saw it in the mansions kitcken and normal houses aswell.

I’ve included a fix for this here.
