Anything in those missions that I need? I can create an alt just to see the content, but I hate to start over completely unless there's a unique reward or something similar.
Same thing happened to me. I did Cabal 4 first, and now I can't go back to 23c to do any of the other missions. Any way to go back? Seems weird that the game would give you the last mission and allow you to complete it before doing any of the others.
