This has been popping up every now again - activity completions (Ketchcrash more than Expeditions) will not give Savvy to the season vendor. In the case of Ketchcrash, this also applies to loot rewards. In Ketchcrash, I do open up the chest at the end and [i]wait[/i] for the dialogue to end before I exit into orbit. This has been happening since season launch, but I'm guessing it's counted sporadic enough that this might be on the backburner.
