Stuck on an island and can't go back

Bug report number 4 120 129 162.

So I was lightning warping around in a cave in a master's daily mission. I warped north across a water channel, thinking I could short cut my way to another area without having to take the long and sinuous way there and back.

Turns out it was an "island" with nowhere to go. That would be fine under normal circumstances, except that I could not warp by to the "main" island because of the slanted view (we can see further north than we can south).

Long story short, I got stuck on this "island" that I could warp to because I could see it from the south bank, but couldn't warp back to my initial point because it was "too far south" of the north bank and I couldn't see a landing point on my screen.
