One bug I always hated that I am mentioning just for the sake of variety is that getting a fastfire after using jjfire 40 times instantly puts you back to the built-in game limit, which means you have to retype it 40 times if you want the cheat again.

Getting stuck in walls is another bad one.

JJ2's multiplayer coding is really, really rough. JJ2 is one of the few games I cannot play online because its coding is so choppy.

Personally I've gotten to the point where the only thing that excites me about this game is the possibility of the source code. If we actually got it and major improvements were made, I garauntee the community would have a huge resurgence. Alas.
