Here are two problems with Lurker.
In the log and the command box in the middle (which contains actions, buys etc.) Lurker is translated as Schleicher, while the card says Herumtreiberin.
In addition to that, when playing Lurker, the command box says "Wen du den Schleicher spielst", which should be "Wenn..." as it is in the log. To be honest, I'm not even sure if that sentence makes any sense here without the second one (from the log: "Du darfst eine Aktionskarte aus dem Vorrat entsorgen.").
