A general update was released for Pooka, Pooka for Settlers, Pooka for Agricola and Pooka Universal that improves communication between Pooka core and Pooka modules.
In particular, uninstalling and reinstalling Pooka would make games appear to be lost. With this update Pooka core communicates directly with all Pooka modules to coordinate the game list, and rebuild it if necessary.
Additionally, deleted games weren't getting deleted in the modules, and as a result of this update may reappear. However, they are now getting properly deleted.
