Hey Silver, Found a glitch that's not game stopping...but it can be quite irritating.
After Shadow joins the party I try to upgrade her Double bladed lightsaber on the Hawk. The lightsaber upgrade screen doesn't come up and the lightsaber disappears from the inventory. It can be easily fixed by upgrading a lightsaber before equiping it to Shadow.
Also, would it be possible to use the Cathar slave as a PC somehow? Could it be done by modifying the apperance 2da?
