I was watching a interview and reading some stuff about, "The Stars Are Left" and it was stated that, if one person bought the DLC their friends could join without owning it. Well my friend always buys the DLC so I didn't save up any money for it. We tried to play it tonight and I couldn't join him. I could join the main story with him, or do challenge maps, just not TSAL. So I know it's not a firewall problem or anything like that. Did we miss something, or did they change it to each person needing the dlc?
Sorry for being a noob
