Unsure if Bug - House burned down but still there?

Burnt down houses leave outlines so that builder pigs (or a player with a hammer) can build it back up. I remember seeing a developer mention that it's an intended effect for guard pigs to be able to burn down everything, since builder pigs will just repair it, but I can't be bothered to find the quote.

 

I don't know about the player house in particular, but I assume that you can just repair it with a hammer like any other house.

Thank you! I do have an update for this though - I saved and quit my game before the pigs were able to repair the house and when I reloaded the save this morning the outline of my house and the other burned down house were completely gone.
