Pretty sure I'm installing them correctly, but the fonts don't show up in-game. Not sure why. :( Using the font pack mod, I can see the names of them in the game, but when I click on them to switch them out they don't appear even though they're supposed to be equipped. Default fonts work perfectly fine though.
Same thing for bike skins. I install them correctly, put the paint files in the correlated bike folders, but the skins won't show up even though they're selected. The game takes a bit to load them in like they're actually trying to load them in, though.
