I really need to know how to transfer a FTB world save to the .minecraft folder in %appdata%. Either that or get the world save from FTB and paste it onto the desktop. Please help!
There's a little thing, though.
If I recall correctly, any minimap waypoints are actually stored in your config folder, so you'll have to copy that over.
And I'm surprised that you're using .minecraft in %appdata% as your FTB install - that's where the vanilla minecraft usually goes. Needless to say, opening an FTB world in vanilla is a bad idea.
