When I customize one of my dragonriding mounts only one stays with the accepted customization all others revert back to the original/basic mog. (ex. when i changed renewed proto and highland to yellow skins, the renewed stays yellow and the highland goes back to blue/basic mog)

LiteMount doesn't (at least intentionally or as far as I know) touch any of the Dragonriding stuff.

I'm not sure what's causing your issue but I don't think it's LiteMount. Can you test without any addons and then with just LiteMount to see if the behaviour is caused by LiteMount? Thanks.

Closing, not LiteMount related as far as I know.
