Excalibur bug!

[alejocorsani]

Hello everybody,
This is my first time playing Tomb Raider Legend, and everything went fine until the last level. In Nepal I reforged Excalibur just fine, and I used it to get out of the temple. Just when the last level started I quit the game, and now that I came back to finish it, I don't have the sword anymore! I searched around the internet, but it seems like nobody has had this problem... What can I do?! I want to finish the game without having to restart it all over again (I never saved)!
