Hello I finished creating this map and I don't know how can I move with orange line. Can someone help me please?😄

Use border tool bro

Don't forget to make a back-up before using the border tool because you will end up creating new borders by accident.

Also you can only move the top right border point in all directions. You have to use the map resize tool to move the other sides, which is very tricky to use.

If you can't get it to work feel free to upload the map so we can have a look. You can paint with textures where you want to border to be, so we can put it there for you.
