Postgame?

So I've done all the sidequest, mainquests and have used all the limited "stamina" and all the anomalies that I'm able to at my current level, but I am out of ideas to actually gain any more Hunter levels.

So is there anything I'm missing that still gives somewhat decent exp and stuff, since fishing is really slow and doesn't give me money if I don't have the City "stamina" or exp as far as I know.

I'm currently Hunter lv32 and Appraiser3 and want to continue to grind on I'm assuming the things I've missed.

Oh I've also done the train till the point it became too high level, and did some prison stuff.

Anyway, any help would be cool.
