Chapter 14: The Tragedy - S2-E6
Audio problem: In the "Previously" section, Mando is shown telling Ashoka; "Bo-Katan sent me to talk to you." But the actual line in the previous episode was "Bo-Katan sent me. We need to talk." (00:00:20 - 00:16:20)
Through the Valley of Shadows - S1-E2
Audio problem: After they discover the rogue planet that they can mine oxygen from, Niko tells Javier and Bernie to inspect the outside of the ship for damage. When the camera cuts to them, you can hear Javier respond in full with a sentence as the camera is focused on both of them, however their mouths aren't moving at all.
