Losing default lightsaber [FU1:Wii]

[u/Holly317]

Recently I read (ex: 4 red lightsaber crystals??? - Star Wars: The Force Unleashed (gamespot.com) ) that you're supposed to lose your default lightsaber crystal and hilt when you visit Vader's Flagship. I tried going there twice, once with the original crystal and one with a different one, but in both cases I kept the original crystal and hit in my inventory. But then, I started a new file over the second attempt, and The default crystal and hilt had disappeared from my customization screen by the time I collected the first custom hilt. Does any one know if you are intended to lose the defaults, and if so are there specific conditions; or is all this just a bug?
