If you need help come to Sim Airport Discord , there we can talk easyer. Link is in the SA steam discussions

If you subscribe a mod , you must start the game new (reload) , only then you can see all your new mods.

Actually all the mod I comment on they don't show in main menu modlist, but when I load a game, the items will be there anyway.
Maybe because old mod? (because the mods you updated in 2023 don't have this problem)

Trying now, will let you know.

Just unsubscribe it , and subscribe it again , that normaly helps (Steam bug)

This doesn't appear in the modlist when downloaded
