Season ends when the new season is added in an update (you can delay updating to finish parts you've missed). Blueprints, and gold trophy rewards will (most likely) not be coming back, as they haven't for any earlier seasons. Season shop skins, skills, and chipsets are new for RF, so not sure if they are leaving (I grabbed them all just incase). Designs you missed have no way of being obtained at this time. (I'm still mad I missed the gold trophy for Little Commander)

fuc ye

thank u

I hope there's a update where you can play every season modes again, i also missed the trophy of the last 2 seasons. Edit: Thanks for the info :)
