So I got my first extract or kill enemy VIP and I chose to knock him out and carried him to the evacuation zone. All enemies were dead so no damage was taken by the VIP. When the last soldier was evacuated, Central scolded me for killing the VIP. Then the mission summary shows an alive and well VIP but the text claims I neutralized him and that "you can't get information from a corpse". I got supplies but no intel from the mission.
Has anyone had this problem?

Apparently this is a bug that has been reported. Here's a thread discussing it.
Based on a post in that thread, it seems that this bug was introduced into the vanilla game alongside the patch that implemented Shen's Last Gift.
However, it also seems like the bug is related to having your last soldier to be extracted also carry the VIP.
If you are able, I'd recommend reloading the last save (you should still have a save from that mission), and having the soldier who is carrying the VIP get extracted not last.
Here's another thread describing the same issue. A comment recommends making sure to hear the entire "extraction" dialogue prompt before tabbing to your next soldier (not sure if you did this, but seems worth mentioning).
