Once your town falls, there is a week of invulnerability so that you can reclaim it before others can claim it. It would cause less people's hard-earned towns to disappear completely, and should be able to salvage some of their stuff. Also, it'll promote people to play more during that week and get their town back up, after claiming.
How would you get to your fallen town?
/t spawn brings you to your old town that fell, so you're able to find and bring it to life again.
Comments?
It'll make raiding harder though.
