Help with 99/100 priorite and 99% koboh

I am trying to get star wars jedi survivor on 100% completed, but on koboh it says 99% and not 100% and there is one missing priorite shard missing so i have 99. and i dont know how to find the last one. i have been looking in forward control tower and on the wall, i have completed all holotactics, all chambers are explored, phon'qi caverns are explored and on ramblers reach i have 37/37 and all other places i can see there are no icons of missing collectible when i have all map upgrades as well, there is no tressures and im going crazy. Where is the last one?
