That shouldn't happen, but Elmsdor had that problem too, so I added an extra check, usually happens when:
if your case is different, would be cool if you can send me the savegame before it ends (you can rollback from the credits and save).
So far with Elmsdor help we were able to get all the endings except Earth Sweet Earth - if anyone managed to get it let me know! it seems either VERY HARD or perhaps impossible
(if is impossible I mean I made a mistake while checking some variables).
I think will leave the possibility to play in both modes even in the final game, so everyone can experience the game how they want.
