Quote from the dev team:
We think we've found the bug, but to truly fix it we'd need to release a patch. In the meantime if you run the game -console, load your save, and before you jump aboard the boat to escape the society bring up the console and execute the following command:
If you saved Johansen:
Code:
SaveJohansen()
Then to level transition if you're anybody but a Nosferatu:
Code:
changelevel2 la_hub_1 taxi_landmark
And if you're a Nosferatu, instead use:
Code:
changelevel2 la_hub_1 sewer_map_landmark
Goddamnit people, how hard is it to just be helpfull?
This solution worked for me, but when speaking to the Prince afterwards, I can't say anythinh about the quest en when I speak to Becket, he thinks I haven't been there yet! My quest log says I have to report to the Prince though. Very odd, I can't get further in the game now.
