[1.0.1978] Home area expanding on trap-rebuilding after boomrat dies to trap

[Eterm]

With "rebuild structures" turned on, if traps are rebuilt due to that mechanism (such as a boomrat dying on the trap and then destroying the now not existing trap. (I can't figure it out, but it's always boomrats)) then the home area auto-expands when a hauler hauls materials to the blueprint (but not when the trap is actually built).

It drove me crazy trying to work out why the home area expanded sometimes and not others but I finally saw it happening live.
