So I'm doing Katzenstein's Lab in Marleybone, and I'm really confused at the end. I talked to Watson and he told me to go talk to Grunk. Before talking to him, I defeated Dr. Katzenstein and his minion. After I constructed the clockwork, it told me to go back to Watson and talk to him. But when I follow the quest arrow, it says that I'm standing right in front of Watson, but my screen literally doesn't show him. I tried spamming the "x" button near that spot, but no luck. I retried the dungeon and it did the same thing. Then finally, I restarted my laptop and did the dungeon over again. It still did that same thing though.
If anyone can help me on what I'm doing wrong, I would really appreciate it!
