Master Spellcaster (use any infusion spell) resets randomly - it was 27 one minute and the next it was reset. No torment change, exiting, etc Has happened at least twice before but I was paying attention this time.
Night Terrors (local events with Mastery) - did not get credit for an immolition event with mastery on the third dungeon. Now this could just be it doesn’t account multiple event in the same escalation run, but in that case fix your description.
