I have finished Katzenstein's Lab and got quest from Watson to meet Sherlock Bones inside the Museum but everytime i go to the Museum Sherlock Bones is never there. So i can't finish the Big Ben. How to resolve this? Please help. I have finished all side quests in every part of Marleybone and no more npc with yellow question mark or exclamation mark above their head. The quests left in my book are the cat quest from Zeke, the history book, and the instruction from Watson to meet Sherlock Bones at the museum. Anyone has same problem? This never happen to me on my old wizard. Any help or info appreciated. Thanks.
