map survey option now causes (fatal) error
For a few maps in a few surveys I have been using the -survey option to constrain map statistics to match the underlying survey (page 34-35 of Therion Book). I think some recent version of Therion has broken this. The start of my map definition. map MiddleEarthElev290Map \ -title "Middle Earth and<br>Lower Greenlink Caves<br>Elevation looking 290 deg" \ -projection [elevation 290 deg] \ -survey MiddleEarth # survey option forces map statistics to match the survey The error reported. via Mapiah.

Thanks Thomas Unfortunately I don’t know how to install or run from a commit or pull request that does not seem to have an installer. I found my way here, but nothing there looks like a Therion install I can run. Fix crash with circular map reference · therion/therion@54c4a9a <https://github.com/therion/therion/actions/runs/24804177732> If you have any tips that would be great – I’ll be unavailable for about four days, so no immediate rush.
