It is silly, if this was my main town (that I don't TT) and I played daily and no one moved for 2 months I wouldn't be happy.
I don't understand the whole backward travelling use. The game doesn't register it as a time gap or anything, just a backwards step, people are marketing ideas on coincidence. And I prefer to go forward so I know how many days I've covered and it means I can pick a couple 3x3 bits of hybrids by house and collect new ones daily as I go. (And I usually set clock to 5:58/59, so I only have to change time every other load and can still get told who has boxed up every day.)
