My friends and I just did a Hadros Lux raid (me on two accounts/phones, and two other people). At the end of the raid, we won but lux just lay defeated indefinitely:
When we refreshed the game, all four of our phones briefly pinkscreened, then went back to normal. We were not given any rewards.
Upon restarting the game, we were not given the “missed rewards” message and did not receive any DNA.
