It's caused by travellermap outputting colors in html code format, something it didn't do when the tool was written.

See this topic (from the linked post and onwards, the posts from this year) for some more information and workaround.

Mappy Birthday!

It's a very nice temple. I don't think I particularly prefer any of the roof or offering options. They all look nice.

My main issue with the map is the grass around it. The scaling makes it look very repetitive. I would consider changing the scale of it a bit, and perhaps try to fill out the areas a bit so you don't get those large unbroken areas of plain grass. That do apply a bit to the paving around the temple area as well, perhaps change the scale so they don't repeat quite as much.

If you use the symbol catalog template, it starts with basically nothing to be able to create clean catalogs.

I've always found it best to just think about what you have good ideas for. A map always ends up best if it starts with a good idea, rather than just start with a random area. So just go through the map in your head, think a little about what you would put there if making a map. Then decide if you have a good enough idea for the larger area or not.

You can create a new map the normal way, and then just use clipboard copy to copy over the entities you want, and then trimming away the parts you don't need with tools like :CC2BREAK:/:CC2SPLIT:.
