Not this way.
Directly in the files.
Do not go through the CMaster.
I think it's in
Bundles
World or content
and kits
find them with their ID
For the away jersey, for example, you have to replace it 3 times. 3 different files.
It is essential to change the kits at the source otherwise it will make bugs crashes
I did as you said but the kits still do not show up in the game
making this way without use the creation master only appears the import and export buttons
no appears button to save
I put three files for each part of the three milan kits
I think I did everything right but milan kits do not appears in the game
what I do not think normal is not have a save button
Sebbastos please give me an idea
