so what worked for me was running the compatibility troubleshooter.
I also have that problem, I couldn't do that quest because it won't let me out and I had to close the game. It is in one of the abandoned house in the London area. Hope they fix it if it's a bug.
Have you been able to finish that mission?
thanks for the info.
Thank you very much for information 🙂
Agree, i'd love to see an editor over an onclick insane amount option. I hope they include this on the trainer.
