I have installed v2.0 as an update via the App Store.
The game is now reset back to ground zero.
Each time I try to link to my Game Centre, (bottom left side of the opening GC account, followed by “An error occurred while linking the account”.
I have tried uninstalling/reinstalling, same result. I will try a restart on the iPad, as a last ditch attempt.
My assumption is that reconnecting to the Apple Game Centre will restore the previous (pre 2.0) state.
This is so frustrating to lose all the investment (time and a little money) to this point. If I cannot relink/restore my previous history, I doubt I will continue.
