Hello! While using this tool, I've found a couple bugs and/or oversights:

• Loading saved files doesn't seem to work properly. Either the program gets into a "corrupted" state (the map display always says "Invalid Parameters"), or the nodes and paths in the map are restored to the incorrect positions (it looks as if the positions were scaled down)
• The "Max Perturb" parameter for paths seems to do the inverse of what it states - a lower value causes the path to be more unpredictable, while a higher value causes the path to be more regular. This might just be a case of unclear documentation though.
• Changing the map dimensions doesn't seem to preserve the "Zoom to Fit" toggle's state. If the dimensions are changed, the internal state of the toggle seems to be automatically set back to "true".

Hmm if you can send me your save files that don't work I can try to see what's going on. I imagine the first and third bullets are the same issue.

I probably had the perturb thing inverted in my head when I was making it and never bothered to fix it. If I do an update with a fix for the save files I can fix that as well.
