Things should be created in data.lua or data-updates.lua, data-final-fixes.lua is meant for adjustments in response to changes by other mods etc. My WIP-version of minime won't scale Shrek because the character is created after I've scaled the characters in data-updates.lua. It would be nice if you could create the character in data.lua:

-- Make character and corpse
require("prototypes.shrek_character_animations")
require("prototypes.shrek_character")
require("prototypes.replace_sounds")

Bumping for visibility, it would be nice to see this fixed so I can add shrek to my multiplayer server!

I was bored so I went ahead and made that change, plus I added minime to the list of character changing mods so it doesn't overwrite the main character anymore (as funny as that was.)

Feel free to pull those changes back to this branch if you get around to it.
