Tallowmere 2 uses a plugin called CloudOnce that utilises iCloud's key-value storage system, with the intent of allowing file syncing between iPhone, iPad, and iPod Touch devices.
Post-launch, it was discovered that iCloud's key-value system has a 1 MB storage limit per app.
This is fine for one or two typical saved game files, but the 1 MB limit causes storage errors once file sizes exceed this limit, which does happen.
There currently aren't any suitable plugins for the Unity game engine that allow access to iCloud's CloudKit or Documents systems, which do not have such storage limits.
As such, for the interim, iCloud key-value support will be phased out for saved games. Existing saved games in the key-value system will be downloaded and stored locally if possible. Going forward, new saved games will be stored locally until further notice.
