I believe that there is a memory bug that is causing random quest to fail,
ie. on the first game , after Jade had removed the rock blocking the catacombs,
Going back as Drake , the catacombs were open and I could see the Doll.
But to the game it was as if the catacombs were still blocked!
Tried going back to an earlier save but it did not work,
It now always shows the catacombs as open even when there are still blocked!
Did a clean wipe (Deleted all saves etc) reinstalled the game , finish all Drake except catacombs,
stared to play Jade and this time "Bloop bloop" has the same problem! (Had completed this quest before)
