Easiest solution: your demolition timer only starts after your subscription ends. So the people who suddenly became preoccupied would know exactly when and how long they have before demolish. And generally if we have a subscription up we'll probably continue to have it up for some time. This provides leeway for people who actually need it. I'm not even asking SE to give extra subscription compensation time to people because they can't play the game. I'm just saying, if they're still paying ... you don't want to give them a reason to stop, eh. Please consider adding this rule and leeway for all future demolitions.
