House Auto Demo'd when I've entered Recently

[Canadane]

I've seen many stories like this and I'm assuming support will do nothing.

Yeah there were a large amount of people who thought there was some housing timer glitch going on.
SE had to do an investigation and came down and (in more polite words) said people were just bad at knowing when they actually used their house.

So there are indeed many stories about this, but essentially they were all wrong in the end.
