"Unknown region", I'll show you "Unknown region"...
Look! Region "Unknown"! How can a region be "Unknown"?!?
It's purely the most frustrating thing EVER--port someplace, halfway there, drop into the "Unknown region"--and CRASH!
It's been three days of this! I want this to stop!
In the meantime, may I present--the Telecalculograph! (There's even a video link to the furnace in action.)
