    Hey,

    wollte vorher die neue Minecraftversion 1.9 ausprobieren. Jedoch hat sich dann beim Singleplayer mein Minecraft gescrasht. Dachte mir nichts dabei, wahrscheinlich ein Bug oder so, und bin zurück zur 1.8.9 gegangen. Als ich dann meinen Standard-Server joinen wollte, kam diese Fehlermeldung: java.lang.NullPointerException: group Hab also Optifine gelöscht, ging immer noch nicht. Java neu runtergeladen, ging auch nicht. Schlussendlich habe ich sogar den Minecraft-Ordner komplett gelöscht, Minecraft deinstalliert und neu runtergeladen, geht immer noch nicht. Wenn ich bei einem Singleplayermodus joinen will, crasht sich mein Minecraft komplett. Hatte das Problem mitte 2015 schonmal und damals auf GF keine Lösung gefunden, also hab ich meinen Computer neu wiederhergestellt und dann ging es wieder. Möchte diese "Lösung" aber diesesmal umgehen. Weiß jemand was ich dagegen machen kann?

    Crashmeldung:

    // Surprise! Haha. Well, this is awkward.
