Okay, finally getting around to playing WiH through for the second time, and I finally discovered the checkpoint option for the mission.
On the last playthrough I did reach checkpoint 3, but was unable to dock with the Indus because of the closed landing bay door just as it got fried by the Tev bombers. I downloaded the patch so hopefully that's fixed.
Now I want to give it another shot & use the checkpoint to reset to CP2, so I make the selection from the comms menu, but it doesn't reset the mission to the last saved point!
Can someone tell me what I am doing wrong?
PS - I'm using the new fred2_open_3_6_17_SSE2_BP and have downloaded the updated version of AOA if that makes a difference.
