It is beta-version! Some problems with animation!
You can use only one one-handed lightsaber!
Game can be crash when you select your character!
Are the following the things you are looking to get fixed?
If so the first 2 likely can't/won't be fixed as we have yet to fully crack model animations for the game or to be able to change nihilus saber wield animations.
The 3 glitch is caused by a hardcoded element within the engine and character selection and also cannot be fixed.
