Hello,
not sure if it's a loca mistake or if it's the case in any language. if it's a loca mistake, please move it.
When you do the quest for reputation badges at Polis Leighton (119143) and you start the green quest, he sometimes says:
[10:33:54] Ihr könnt jetzt zu Grünes Schwarzes Brett von Silberquell IV gehen und Euch die Quest holen! (You can go to the green board IV)
But it's actually green board III and not IV.
Greetings.
