Hey there @rturn2_2000 !
Thanks for reaching out, agent! I understand that you are unable to access DARPA - I've reported this on to our teams for further investigation. If we have additional questions, we'll be back in touch on this thread.
Regarding the pending mission to access and listen to a computer in DC, could you please provide a screenshot from in-game showcasing the request on the map for further review?
And finally, with the tombs issue, could you please provide a short video showcasing being unable to exit the area after completion? You can upload this to any popular video sharing website such as YouTube, Vimeo or Dailymotion and provide us with a link.
Let us know how you get on!
