Sealed Fire Temple - Shortcut or Bug? (FS2 v0.29)

As the map of the Sealed Fire Temple currently stands, there is a shortcut ladder that bypasses the vast majority of the map (and skips the Sealed Fire Temple II cave entirely). Is this intended, or was it an oversight when editing the Temple map for this usage?

Under the spoiler tag is a 3200x3200 image - the entire map of Sealed Fire Temple. It is HUGE.

Spoiler:

oh gawd. Such a big picture! O_O'' Did you actually screenie all of this?
Anyways~ I think the ladder should have been there... I think that the 2nd way was for the underground dungeon? I forgot... not sure. xP

Yep. Pasted together more screenshots than I could count. Very tedious, especially in the areas with the SIOE's chasing me.

Strategy tip:

Spoiler:

And I'm not sure. I went all the way through the entire dungeon (including the cave connecting points A & B on the map), and saw nothing that would justify taking the longer path if the shortcut is meant to be available. Anyway, I suppose only Zeru knows for sure, so we'll find out when he shows up and offers his opinion. That one ladder makes the entire path I marked in yellow extraneous, which doesn't seem reasonable to me.

nice guide :P
doing this for hein's castle would probably be a pain xD
good thing I did a guide for it already lool
