[Therion] Limit on scale

[Andrew Atkinson]

I'm working on a survey

http://www.cave-registry.org.uk/svn/CheddarCatchment/Bagpit/

As I'm working on it the Head will be changing as often

Using the config file in this directory it works at a scale of 1 100

However if I import common_layout.th (which imports another file) from

http://www.cave-registry.org.uk/svn/CheddarCatchment/

Then use the common layout in my local layout, I get an error if I try
to go to a scale bigger than 1 139 (eg 1 138) The message does not give
me any clues, as far as I can fathom, of what is causing the error, and
there is lots going on in these files, some very old now, so how do I
find the problem?

The error message is
