This is not a cause for alarm, we just want to inform you of the following details regarding this mission.
Please be informed that for completing the final task of the mission #3 in the Hunt for Bismarck campaign players are credited with Secondary Battery Modification 1, which is an incorrect reward and it cannot be mounted to any ship. With 0.6.5.1 patch release next week the reward will be changed to the correct Auxiliary Armaments Modification 1.
After that we will remove the incorrect upgrade from the accounts of players who have already received the reward, and credit the correct one instead. To avoid loss in credits, we are asking not to sell the incorrect upgrade, and wait for the 0.6.5.1 patch release to have it changed to the right one. Players who have sold the Secondary Battery Modification 1 will not get it exchanged.
We thank you for your patience and understanding.
