My guess has to be with the way the switch adds the mods the (layeredfs) we probably need to add the mods directly into the game itself like on pc but that would take awhile
After just now trying to add a mod for colourable tails based on the character's hair colour I'm met with very consistent crashes.
The mod has the capacity to load but more often than not I wind up with the "The software closed because an error ocurred." message.
Specifically, I've got it over the regular Saiyan Tail accessory, the same as before, but the only reason I can think of that makes any sense is the difference in code between versions. Though that doesn't explain why the game still occasionally loads the images of the character with it... It's pretty odd...
