Eigener Schlag zeigt beim Brechen keine zweiten Splitter

Der Kern meldet einen Schlag, der Fels bricht, nur als geänderte Kachel
ohne Spieler. Die Hauptszene merkt sich deshalb die Kacheln ihrer
eigenen Schläge, bis der Kern sie meldet, und zeigt dann keinen zweiten
Splitterwurf. Als Gast kam der zweite eine Rundreise später und sah
wieder verzögert aus. Splitter gibt es nur noch auf Fels, nicht mehr
außerhalb der Karte.
