Players not kicked out of POH on server shutdown, ending up in white void when they log back in after daily reboot

Ryan asked me to file this as an issue report (although I think may actually better be an RFC, since server reboots aren't authentic? I'll be happy to edit the title if that is preferred).

What I did: Be inside my POH while the server reboots (I did this locally now, but the daily reboot in the live game produces the same result). Log back in when the server gets back up.

What I expected to happen: To find myself outside of my POH at the entry portal. This is how it works if you're in the Fight Caves or in Bork's room when the server reboots - you get booted back to their respective entrances.

What actually happened: I was stuck in a white void when I logged in (because I was still in my POH instance, which the server had not set back up for me, since that only happens on entering the house).
