this is info for those of you, who are working on getting that Super Pershing of yours through the mission. Currently, the hangar mission window is bugged. When you finish one of the partial nation missions (for example gain 75k XP for Americans), the mission counter resets and the mission will start “anew” (picture courtesy of e4gl3m4n):
Please note that according to WG EU info, this is just an interface bug. You won’t be rewarded for fulfilling the nation mission twice (gaining 150k XP for a single nation won’t get you ANOTHER 2 days of prem), nor will it count towards the Super Pershing goal twice (you cannot for example get the XP require for Americans twice and skipping for example Japan completely, you really do have to get 75k XP on each).
