While playing a freshly made Sith Warrior with the Assassin combat style, the first quest had some inconsistencies in the cinematics. Particularly when retrieving the blade from Ajunta Pall's tomb. The weapon looks like the normal single-bladed weapon that's always been in this cinematic even though my character uses a double-bladed weapon due to their Assassin combat style. Despite looking like this, the quest still rewarded me with a Korriban Battler Practice Staff, a double-bladed weapon that looks nothing like the blade in the cinematic.

Slightly unrelated bug report: The Korriban Battler Practice Staff uses the sound effects of a lightsaber when used in combat instead of an electrostaff. The Apprentice Practice Staff your character first starts with sounds normal.
