To start with the basics, you're probably not wanting to use the Symbol fill at all. It is a very ancient way of filling with symbols, and only gives a very regular pattern. You're probably want to use Draw -> Symbols in Area instead.

Not sure about the crashing, but I am able to reproduce it, so I'll bring it to the attention of the developer. But this fill type is likely to go away in the future, so a fix is likely to be lower priority.

No. It's a holiday, so both Jack and Asa have some time off.

Try this workaround:

Also note that both CONTOURSM and TRACED are commands that does this automatically, none of them require tracing by hand. You probably do want to use TRACED (after applying the fix from above)

This livestream I plan to teach you all a bit more about combining styles. I have shown elements of this before in many of my live mapping sessions, but this time I am going to make it a focus of the stream, and give a more complete and coherent overview of the process.

We will talk about thinks like setting up your own template that combines the resources from two styles so you can have everything at the ready when you make a new map.

As usually, you can visit https://youtube.com/live/reoS0Mzlnzk at the appointed time (which you should see in your time zone in the left forum sidebar) to watch the video, or use the player below.

The hyperlink consists of 2 entities, the link itself (Which is normally invisible when you load the map, make it visible by View -> Show Hyperlinks), and a purple rectangle which just shows where the hyperlink is.

Both of these can be deleted by the regular erase command, BUT the HYPERLINK layer may be frozen, in which case you need to thaw it before you can erase it.

Also note that they should also both be on the LINKS sheet, so you can also just hide (or delete) that sheet.
