Try this way.

Boot your computer up, save thd map.

Don't do other things.

Does it still crash out ?

I suggest this to give cc3+ full access to the computer's memory and cpu.

I use those clouds in dungeons for fog. I've also added them into overland maps I had already made. Easy to use them for fog, as they are on their own sheet.

Thank you. I have uploaded the pngs to my site, and created an overall map page, clicking on a small map leads to a larger map.

I went ahead and did it. I had to move a few things to get roads to line up.

Overall map first, lower three rows.

part 21 added a few bits.

part 22

part 23

new bit and the last part to be made.

part 24. Added more bits.

part 25

Took a bit to line things up. But I didn't try to line up all roads, afterall, this is an evil city.

Part 20. The bottom road matched exactly. The top on has to be adjusted a bit.

Similar to part 15, but I made some changes.

overall.
