Timer for housing relocations

[Conundrum]

Because relocation doesn't remove a housing plot, it's a net neutral change, one plot for one plot. You can just find their old plot and try that one instead.

It's not neutral.

It gives the current house owner priority for getting the better house (or else they wouldn't be relocating).

It also turns the newly opened lot into a scavenger hunt to find.

Finally it resets the timer.
