[REPRODUCIBLE GAME CRASH ROLLBACK] Raven's Reflection Quest Bug

Raven's Reflection Quest reveal (when completing delirium map boss) crashes the game and rolls back the map. It has happened to me 3 times in a row now. I've lost a Divine and multiple T15s because of this. I've also tried going back to my hideout before clicking on the completion marker and stored my loot but going back to the map and clicking on the completion marker still crashes my game and somehow still rolls back the loot I placed in my stash. Please fix.
