After dragging myself through Trials again (rng still sucks very very very badly btw, burned through over a dozen engrams to focus the Immortal and still no godroll dropped), I returned to Saint-14, who gave me the "Trials of Osiris (Weekly)" pop up message but no loot. When I hit enter the message disappears, but reappears every time I interact with Saint. Issue found on PC. This game mode is hell.
