the bars resize, depending on how much of one you have compared to the other. for instance, if you have 100 paragon and 50 renegade the bar will be much bigger for paragon than the renegade. as you decrease paragon but remain the same for renegade, the renegade bar will 'appear' to be getting bigger. this is the only thing i can think of that might have caused what you describe there-
i double checked my code to make sure i didn't goof.
1) savegames 2) clear instructions how to repeat the problem 3) if you have DLC content added to your game, likely i will have problems using your savegames 4) might be nice to have a copy of your game executable MassEffect3.exe 5) when you say 'retail', you mean your game came in a box with dvd and does not install origin, correct? or you got it 'elsewhere'?
the only savegame i got so far was from a person who was using the wrong trainer and was having crashes immediately when loading the game (which they finally figured it out that they had to use the other trainer). i've only seen TWO executables for this game so far, so I am a bit confused why some people would not have success with the credits option if the other options are working right..
