I am experiencing the same problem, with debris (not original Therion one). I realised, this error depends mostly on density of rock pieces drawn in the map. While high density crash compilation even 0,5 km of passages, with lover it works well with large caves, even the amount of pieces is much bigger.<br>
I think it is because unpropriate syntax of area.<br>

This sounds familiar. The following forum thread lead to a bug<br>
discovery in 5.2.13 in around 2009.<br>

<br>
But I assume that is not what is going on in this case.<br>
<br>
There are some other threads that might hold clues, but I don’t have<br>
any helpful suggestions sorry.<br>

SUBJECT: [Therion] Scale dependant error when using area fills<br>
<br>
Hi all<br>
<br>
I'm having some problems compiling a project which includes debris<br>
area fills. Depending on the exact symbol fill that I use, I am<br>
getting strange scale-dependant errors which seem to cause the<br>
compiler to loop endlessly until I force it to stop.<br>
<br>
I originally noticed the problem when using a custom area fill that I<br>
made by modifying the standard a_debris_AUT symbol fill. I've attached<br>
my modified metapost definition in the attached text file<br>
'a_debris_WUG.txt'.<br>
The error occurs for any scale between 1:2000 and 1:4483 (outside of<br>
this range the project compiles fine).<br>
<br>
See attached output log 'Output log - a_debris_WUG.txt'. As you can<br>
see, the file seems to loop over and over again.<br>
<br>
Initially I thought this problem was specific to my custom fill, but<br>
then I noticed that I also get a similar error when using the standard<br>
a_debris_AUT fill, however this time the error only occurs when the<br>
scale is set to exactly 1:2000 (any other scale seems to be fine).<br>
<br>
See attached output log 'Output log - a_debris_AUT.txt'.<br>
<br>
Can anyone help with this problem?<br>
<br>
Thanks<br>
<br>
Tom<br>
