It doesn’t show up in the custom campaigns menu or in skirmish maps
Yep, I know now, but five minutes ago I didn’t, because I thought that after someone helped me on the forums everything would work, and I trusted them. Big mistake. It still wasn’t working and was even more broken than before. I’ll remove it in a few days and wait until I have the entire campaign ready to publish it properly.
I find it quite good so far, really enjoy the RPG-elements of it! It worked well, until I went either back south, north or to the cave, because I couldn’t attack the enemies waiting for me there, and they just overran me eventually.
Your mod isn’t working properly because the path is wrong
You put the game and scenario folder into another folder
Please remove this folder to ensure everyone can access and enjoy your mod 
Example of a correct path : C:\Users\XXXX\Games\Age of Mythology Retold\XXXXX\mods\subscribed\286944_tower defence\scenario
thanks, i will try it, it’s my first time doing maps and it’s very complicated
