That's a shame; I kinda want a complete style with this look now 😉😁! Could be a lot of new Annual issues in it, Sue 😎!

Too late to be of much use now, I realise. However, dashed lines, even when you've adjusted the settings to give suitable lines and spaces, often need minor tweaks after drawing them, as has been mentioned already. As Sue said, simply adjusting one node on the line by a few pixels is often enough to stop the unwanted "looong" line segment, or occasionally removing one node, although I find the line adjustment method is more reliable, and easier to correct. Of course, you have to check the whole line, because correcting one spot may create problems elsewhere. So again, I often draw any lines like this in shorter stretches, to keep such difficulties within manageable limits.

The problem seems to be commoner when you have a couple of nodes quite close together in one part of the line, so again as Sue suggested, keeping the number of nodes overall as low as practical, will likely help. (Except when it doesn't, of course 😉!)

Well, if that isn't the catalyst to have them go visit the OTHER city, I don't know what is 😉!

Have to say when I first looked at the floorplans, I wondered why they'd built a mint with no real security - all those walls with massive holes through them! But then I looked a bit closer and realised they were actually windows 😁!

So we can expect to see more fossils in Sue-designed dungeon styles in future then 😉?
