What do you mean by that? Did the sky in all of your maps change, or just in the map you downloaded?

If it changed in all of the maps: Just delete the map you downloaded and all of it's components.
If it changed in the map you downloaded: It was probably meant to be like that. xD No worries.

If it changed for all of your maps then whatever map you downloaded probably named the sky the same as the default sky for FH and you clicked replace. So whatever their sky looked like now all your skies look like that. Just a suggestion
