Even if you didn't, it makes sense to have the auto-void system in place since it helps from you being held up since you won't have to stop with EVERY villagers that's in boxes.

Same with only having reservations under special circumstances. It's seriously a PAIN to keep track and you really do get held up if they're in boxes and the person isn't around for a while... >.<
Yeah... my main town's been semi-neglected. I know Stitches tried moving and I wouldn't let him. "No. After all the trouble I went through to get you, you are NOT leaving until I say so!!" XD
