There was a similar issue fixed in the PC version, which will be in the next console patch, but the destination was different (start of Whispers of the Void, rather than the previous section of the End of Time). If this has the same cause, it may also be fixed in the next update.

Did you try loading a save before defeating Leandra and choosing different options at the end (not performing the soul forge, leaving the sisters behind, etc).

Hi, I'm the other player of that co-op game and I'll try and give a better picture of the problem.
-We're playing the PC version of the game
-After going through the teleporter after defeating Leandra, we're sent to the correct area: the area of the first garden with the death knights, but one of the main characters is forced into a conversation with Zixzax despite Zixzax not being in the area. Zixzax asks if they're ready to leave, and the only option is 'continue', and after choosing that they're stuck in an empty dialogue box with a greyed-out 'continue' that isn't choosable, so the conversation can't be exited.
-The other main character can progress on and trigger the death knight fight as normal.
-Attempting to forcibly kill the character trapped in dialogue immediately brings the whole party to the start of the first garden again; the place you end up after agreeing to Zixzax normally the first time, but the giant Leandra events don't replay. Attempting to progress from here leaves us stuck at an unresponsive teleporter gate a few areas later.
-Attempting to kill the character before using the teleporter makes no difference, they're forced into the dialogue even as a corpse.

We've tried choosing not to restore the soul forge, or leaving the fusion behind, to no difference.

I've created a report.zip file and will send it to the support email with a description roughly the same as this one.
