So I went up a New Monarchy rank, received a weapon, a ship and motes of light and strange coins. Apparently something else dropped because I had the notification over the postmaster telling me there was something to collect (it wasn't flashing before). The only issue is the postmaster is empty... I've logged out and back in, I've restarted the game, I've even deliberately missed an engram so I could collect it from the postmaster, but the green icon is still flashing despite the fact there's nothing to collect. I have to say it's annoying me more than it should, what's going on here?
