Some users find that if they create a new map, they cannot run the next session of the game. There is a solution to this, if it was placed in a mod folder.
Method 1:
I HAVE PERSONALLY TESTED THIS METHOD.
Most mods have eighteen lines in the Index file. Go to the very last lines and remove the following:
IncludeFile = Base.rte/Scenes.ini
WARNING: Do not remove this from the original CC folders (obvious)
In other words: My very first post.
Method 2:
To run the mod(s) WITH the scenes, insert a Scenes folder in the respective .rte. Thanks, Natti!
