old player of silent hunter 4 but new to subsim

[GreatEagle1]

Hello mates, my name is Thomas who username is GreatEagle1 in the game of silent hunter 4 with steam so would like to find others who play silent hunter 4 multiplayer with the use of tunngle so feel free to reply to this whoever plays this so we can get a wolfpack up and running because I love to sink destroyers very much with my sub and its main guns on board but I have a question for those that play silent hunter 4 and its that when I did one of the missions that after I went to photograph the harbor that is yellow then went back to the main harbor I came from that it shows there that I cant end the mission so is this game bugged or is there something I am missing ? I have photographed the harbor and also clicked on the button when I was on top of water but no additional mission so what am I suppose to do now with my career ? Any suggestions is appreciated, Thanks. GreatEagle1
