Can you add in some images of the Power room during the self-destruct sequence in the original game (either scenario, but preferably Jill's scenario, her best ending specifically)? I'm particularly looking for the bit where Wesker's decapitated body is found next to the self-destruct panel. If possible, can you also add in the description of Wesker's corpse in the power room?
So I guess you fixed whatever the problem is with your game?
BTW, seeing the image, I'm actually wondering whether he was actually decapitated, considering I can just barely make out Wesker's head in that image and it's near the shoulders, indicating it's still connected.
