I have a similar question, so I will not start a new post.

If I have a 3-stairs-warp (as in the original NES-Zelda), it works perfectly.





But with a 4-stairs-warp I have the problem, that there are not 4 destinations, also not 3 destinations. Just TWO!



Theoretically I can go where ever I won't, but not always directly by picking one of the 4 stairs.

From every starting point I can reach exactly TWO destinations, because always two stairs guide me to the same destination. And I don't know why.

Any idea?
