Hi guys ! Earlier I got helped by some really nice fellow senior agent for the mission 6. But then when I finished mission 6, the game showed me the usual end-of-mission video, and then sent me back the the mission hub. It was flagged that mission 6 was completed, however it was also flagged that mission 7 was too even though I hedn't started it ever! And I couldn't go to mission 8 since it was locked... I solved the problem by restarting mission 7 and it fixed it, so I'm fine now . Thanks for the help
