Hi UbiSailorScout,
I am also still experiencing this bug:
Walk up to the door for Ortega's office, push "M", the little indicator spins, nothing happens.
I'd like to provide you a video, but the using the UPlay overlay causes the game to constantly crash.
FWIW, I'm playing on a Windows 10 rig. If you need my full system stats, I can provide them.
Thanks,
