Not sure why but I didn't get credit from a successful plunder for season points. Not really sure why since on another account it worked fine when I plundered on it. Obviously there are enough times to still complete the mission for the month but hopefully this isn't a wide spread issue that will happen frequently.

Didn't notice until later so the successful plunder message disappeared from chat already. But you can see based on the other pictures that I already had a successful plunder due to wanted status.
