I finished the game, got every achievement, but I am missing the "Objection!" achievement (Throw a Judge's gavel back at him). I found it impossible to find any more judges after the story's finished because I revisited some places to get some missing figments already, so there are no more "big" enemies spawning for me, nowhere. The only possibility I see for unlocking this achievement is playing the game from start on a new save up to a point where I meet a judge, but that takes a lot of time and really seems a bit tedious.

Isn't there a possibility to build some "training ground" update into Psychonauts 2 where you could train fighting against some enemies and thus being able to unlock those various achievements? Or any other update where some judges will spawn every time? I would be very glad :) Thank you.
