I’ve just encountered a bug with a total game freeze. I had to kill it to make it exit and I’ve lost my daily realm progress. I was fighting my last fight to complete the duty and I can’t try it again. That’s weird because my game has not been saved because of the freeze.
It happened after I cast a Mass Dispel to get rid of a blight debuff. It was the first time I cast this spell after 1.2.0. Don’t know if it can be easily reproduced though, I have not tried !
