I completed the assault on Titan yesterday, Chasm of Screams and it did not drop my thorn. Why? Why? WTF WTF WTF What's more, this assault didn't count in my game history.
Did you kill the 2 named knights in final room, or did yall melt the shrieker quickly? If you didn’t kill the knights before killing shrieker, then you didn’t do as quest says.
