I killed the general, and went into the cave where I'm supposed to go, I entered the code (Blue, Yellow, Cyan, Orange), and I went through the door, and through another gate. I got to the place where I have to turn in my mission, and I saved, and quit. When I got back onto the game, I was back in T-Bone Junction, so I redid everything, and killed general knoxx again. When I went back through the cave, to the place where I entered the code, and found that the door was opened already, and the code was already entered. So i went through the door, only to find that the second gate was locked, with no apparent way to unlock it, since the code was already put in. I redid this 4 times, in hopes of the gate being open, only to have my eHopes crushed. Has this happened to anyone else? If so, please help, and tell me what to do :'(
