Happened to me too. I've played ME3 enough times to know that as soon as you load into the ship, Shepard says "I'm inside....", then Tali explains how the admirals voted for or against the geth war. I was able to get the dialogue to trigger by reloading the autosave that happens as soon as you enter the ship. On Xbox One also, btw.

This worked for me as well. Annoying that it doesn't play normally anymore, but at least it's not lost forever. I'll just have to stop and load the auto-save every time.
