Hey there everybody, I'll try to address everyone's issues with this post as best as I can!
@IGotKelsoPreggo and @rosemarykw, the issue you are running into is not a bug. If you do not have the expansion pack for the game, the seasonal content is not available to you and some locations in the game will not be available either.
@As1r0nimo, is this issue with your assault groups happening with every control point or only specific ones? Can you record a video for me showing what happens when you try to capture the point?
@Zebedee_73, are the ammo drops light enough that you're actually running out over the course of a mission? Can you let me know what control point you were finishing?
and @WayaFreja, cosmetic item drops are intended to be extremely rare and if you're already received quite a few they could end up being even rarer for you. If you do not get any for a very long time, that could indicate that you don't have any left to get in general.
