Finally finished the mods (and found an easter egg)
Added 2022-06-04 00:33:45 +0000 UTCI had to completely rework the mods because of the new costume preview button in character archive, but on the bright side this means you can see a preview of all skins (default, S rank, or costumes) in their full colour and animation in the archive.
For those who are using the free mods C class, I found a little easter egg while looking through the new script. In the character archive, if you press the Basic Stats button 20 times, you will enable colour for the greyed out character you are looking at.
