I've been getting 90k'd quite a bit the last two weeks as well. It's ALWAYS in a Dungeon, Raid, or Trial fight though. Doing open world content like Beast Tribe, Hunts, and Logs have been a breeze, but I kind of have to cross my fingers about finishing any group content. I'd say it's been about a 40% chance of getting 90k'd the last two weeks for me. Not sure what's causing this, but it's never happened before.
