Its a way more sensible solution, though?
While I can agree that a better warning message up on logging in would be a good idea, I absolutly see no reason why the devs should start and waste time on developing something that tracks wether or not you entered your yard when we already have a working system in place that tracks wether or not you made the tiny bit of an extra effort not only to step over the border of your property but also invest 30 more seconds to right click that entrance door and take a peek inside. Whats so difficult about that? Even if you only care about enjoying the outside, whats so difficult or horrible about that?
The point of your thread and posts might have been that you wanted to rant (about something that was at least 95% your fault for not following well known rules), but it should have been to come up with a solution to your problem. And quite frankly having a better warning-system - lets say pop-ups during the last 7 days you can save your house stating clearly that you need to enter it through the frontdoor ("One of your estates is schedulde for auto-demolition in X days. To halt the auto-demolition the owner of the house needs to enter the inside of the house through the frontdoor. You can check the status of your estates in the timer-menu.") - IS a good and practical solution.
Everyone who can sit outside their house can spare the 30 seconds every 45 days to enter the house. Its a tiny, tiny inconvenince, but nothing compared to wasting dev-time on a new system that only benefits the lazy and careless.
