As the title says, Superman's missing his voice and subtitles, at least in Earth 3 content. The easiest way to check is to go to Earth 3 Gotham and speak with him there, he's completely silent. All other characters are speaking normally. He does speak just fine in other places, like Hall of Justice in WT and such.
Hi, in the Earth 3: The Visitor Duo, Superman is missing his voice acting lines. He would move his lips, but no sound comes out. Lex Luthor's voice is normal, but it sounds like he's just nattering to himself the whole time, which is pretty funny. Just letting you know in the spirit of being helpful. We've reproduced this bug 2 to 3 times now, with my Duos partner confirming the lack of sound. Thanks in advance if this gets fixed, I hope it's an easy one.
Ran the Earth 3 duo this evening after realizing I had never gotten the drone feat at the end. In none of the scenes (cut scenes and game world) did Superman's v/o play (although everyone else's did).
It's not just the duo, he's also mute in open world and raids. https://forums.daybreakgames.com/dcuo/index.php?threads/supermans-mute-in-earth-3-content.305667/
Status changed to top bug: in progress. This is resolved internally and should make the next game update.
