Bug Report Voracious Resurgence Mission 6-2

Hi. I took a break from Voracious Resurgence Missions and I started to complete them again. My mission log says I'm on Mission 6-2 Nii's Last Stand. I wasn't sure where I left off so i looked on BG Wiki and started from the beginning of the mission and talked to each npc. I didnt receive anything new from the npc so I examined the Aspirant's Grounds hoping to receive the key item Aspirant's Canteen for the BCNM fight wit no luck. I'm lost on this mission and I believe it may have been bugged as I can't receive the key item to enter the fight. I have back tracked several times to make sure i haven't missed a cut scene with an npc but still no cut scene. Please if anyone could provide any information on this please help. Thanks.
