[Therion] Horrific Warping between maps where I want my lines to join

You can force a specific point on a line to join to another specific
point on another line, instead of letting Therion do it automatically.
Give each line an ID. find out whether you want the points at the start
"0" or end "END" of the lines to be used in the join. Then use something
like this:
join line1 at survey1:0 line2 at survey2:END

However, I would be checking whether your scrap has perhaps got some
survey stations with the wrong -name set in them. Causes really extreme
warping when XTherion has accidentally made a bad guess about the
station name within a scrap.

Also note that Therion naturally only joins "wall" lines. If you have
any other wall lines in the area - be they "-visibility off", or
"-outline none", Therion might be trying to make them part of the
automatic joins, forcing a weird warp and a mis-join. (And double check
that none of your fill lines or slopes are accidentally made of a wall
instead.) In such cases, using a specific point join described above is
the solution.

But I will be interested to see what the actual problem is, so feel free
to send me your survey data and I will try debugging it, if you would
like. I'm guessing it is not small enough to send share with the whole list.

Cheers,

Tarquin
