The Slayer.6071

Hi all,I've done 'Living World Season 3, part 4: Head of the snake' now 2 times in a row and both times after completion I get logged out and see the "lost connection to service, please try again later"-error. After logging back in it doesn't count the mission as completed, so I don't recieve the reward... Anyone else had this problem, and maybe even knows the solution?
