Current questions and answers regarding the map editor.

Hey guys. I have a problem. I'm generating a random map in the editor. If I don't change anything on it, we can play online with friends without any issues. But if I change something, for example, create alliances, then no one can join my game on that map. Also, when saving the map, it says: "As you've changed this map, the rmg marker will be lost, and multiplayer regeneration won't work." How can I fix this?
