You will need to modify sceneBattle to not use it. Luna Engine isn't plug and play as you think it is. It's a UI Customizer and the same project is just there to give you an idea how you can do that. If you're using Yanfly's Buff and States Core heavily and using combos, then yeah it can stay.
Yeah I know that it aint Plug and Play. And I am using Yanflys Buff and Status core. I will leave ComboSnip in and will try to use it. Thanks for your help
