Hello again Phosphor!
All 4 of your maps are present in game.
However, it seems like you forgot to remove the map files from directly inside the 'mod_files' folder.
The map files should only be pressent inside the 'mp' folder, not in 'mod_files'.
(Otherwise those said files will still show up in a place they shoudn't be.)

Thx Nibbling Monster, i've updated the maps just like you told me to. Now i understand why they wouldn't show me the maps also. So it should be fixed and thx again for the help!

Hello Phosphor!
Humh, it seems like the map files aren't placed in the right spot.
Just putting the files inside the 'mod_files' folder won't do.
You'll have to create a series of maps in order for the map files to be installed correctly.
(otherwise people can't play them)

Here's the correct path:
mod_files -> Data -> scenarios -> mp
Place the map files inside the mp folder you just made.
(Double check for spelling mistakes when making the folders!)

Just a small note;
If you're planning on making more maps, might i suggest putting all of your maps into a single item?
That way people will only have to subscribe to 1 workshop item in order to have all of your maps.
(For instance: 'Phosphor's map pack')
