This has been announced elsewhere, but for reference here as well: I haven’t been in a position to do the kind of upkeep I would like on Counterfeit Monkey, and consequently I’ve released the full source for community maintenance, at the kind suggestion of Dannii Willis. The source is at Github, and there is an official issue tracker, which is now where you should go with any bugs you encounter. (I will try to go through my own bug report backlog and add the rest to this list, when I have the aforementioned time.)
