Can't Get Free PvP Maps... Bayou Bash instead???

[Dreary Yew]

The 3 free PvP maps just came out, but I am unable to play them. The icons are locked from the stage selection screen, and wants me to "buy" them from the iTunes store, but thy are free, and unbuyable. I was given the Bayou Bash PvP map, even though I never purchased the Ancient Swamps campaign. Can anyone help? I think an administrator is gonna have to help with this one...

They are 'free' in the sense that they are additions to existing campaigns.

"Forest Fight!" and "Forest Tombs!" require Dark Forest.
"Tiny Tombs!" requires Fathom Crypts.
"Corridors of Killin" requires Balefort Castle.
"Ice Tunnels!" requires Frost King.
"Bayou Bash!" has no requirements currently.

Oh, ok. I misunderstood the meaning of "free" in the patch notes
