The website was recently updated, and consequently some things are broken. We will be fixing minor theme bugs in the background over the course of the next few days.
I agree with Gyuszi4, a support of the single player mode would be very friendly. Just like similar mods in SP which allow you to fully customize the lightsaber (double, dual, etc with red light available) from the creation of his character. Edit : Finally, I do it by myself for my own usage... Sorry for the rights i don't have !
