[Therion] Placing part of a map below another

[Bill Gee]

Hello everyone -

I seem to be missing something.  I have made this work in the past, but now it seems that Therion is totally ignoring my instructions.  Argh!

I have a part of the cave where a stream flow under a tourist trail overlook.  The original sketches were done on two different occasions, and I have drawn them as separate scraps.

When I set up the map in the .th file, I created a map for "MainPassages" and another for "LowerStream".  These are then collected into a single map.  The LowerStream map has options "[0 0] below".  However, the compiled map always shows it ABOVE.

I tried adding a "break" between the two maps.  I tried adding units to the [0 0], and I tried changing the offset from [0 0] to [20 20].  None of these made any visible difference in the compiled map.  I tried removing the "join" that connects the lower stream to the main passage, but all that did was make for a sloppy join.  The lower stream was still above the overlook area.

I have other caves where I have done this, and it worked.  What am I missing?

Attached is the .th file I am using.

Thanks!
