It may be difficult to reduce the problem to a minimal sample; if I
change anything the survey compiles without errors.  I have tried:

Changing the scale (problem only at 1:1000)
Commenting out scraps (problem goes away if any scrap is commented out)
Using different symbol set (problem goes away if default symbols are
used rather than my customised ones)
Commenting out custom symbol definitions (problem goes away if any
custom symbol definition is commented out)
Selecting more maps (a map that contains the 'problem' map compiles at
1:1000 without errors)
Removing non-selected maps (if comment out in the master .th file for
the area maps that aren't selected in the .thconfig file that causes
the problem, it compiles without errors).
Compiling other parts of the system or area works OK.

So - it looks like if you want to see the problem for yourself, I'll
have to send you my whole data set (which I'm quite happy to do) along
with my symbol definitions.
