The longest message i know you can get (in the chat) is the equivalent for "<t> is not a valid target.":

"Der Unterbefehl [Name des Ziels] an der 2. Stelle des Textkommandos (<t>) ist fehlerhaft." - which basically translates: "The subinstruction [Name of the target] at the 2nd position of the textcommand (<t>) is faulty."

So no real clue what he's talking bout, two friends of mine both play on the german client and don't really remember any multiple liners directly on screen :x
