I've done the new duo twice for the Dark Knights episode and not once have I seen a headline for it. The headlines for the other two events worked just fine but I don't know why I didn't see one for the duo.
I did the duo again on Event and that gave the headline. Despite having previously done it twice on Normal though, I didn't see a headline for it until then so that should be looked into.
I’ve been running the normal version of the New Apokolips Duo. Today I ran the Event version and got the Apokolips Now headline. Apparently the normal version doesn’t grant it.
I searched for Apokolips Now headline and didn’t find anything, so I posted. But I now see this reported before a few weeks ago as “Dark Nights Duo Headline Missing” five pages ago.
