Then you need to work outside the map.
Configure the advanced map editor, configure the desired table (Google will help), go to Resource=>Close MOD so that the changes are saved to the root of the game, or Resource=>Unpack MOD to unpack the map and create it there.
All paths are stored in the index.bin file, and when working through the map, it is cleared each time it is opened.
Thank you, I understand - it's an unnecessary effort. It's easier to copy and paste the path.

Could you tell me where to find a list of tags that are available for text displayed in a MessageBox? I've seen it somewhere before, but I can't find it again, and I only remember h1, etc.
