In interior structures (caves, houses, etc.) it is possible to "telepoof" using the Lazy Explorer outside of the intended playable area.
I used the console to spawn a Lazy Explorer into the game. Right now I don't know of a way to legitimately obtain it, and I believe this issue is currently limited to cheating with the console. However if it is obtainable legitimately (such as being able to link a Hamlet world to a vanilla/ROG world) then this exploit will become an issue.
Use the Lazy Explorer to Telepoof outside of the intended playable area in an interior (such as a house or ruins) structure.
