Interesting. To counter that, here is this short 1min video I did with the original game in DOSBOX (game files from GOG):
https://www.youtube.com/watch?v=TIjBRZ5WlX4&feature=youtu.be (sorry, no recording software so just used my phone).
You can see, that in the first clip even though I don't have alien containment, I get credit for a 1 live alien recovered after stunning a sectoid (even though I stunned 2). HOWEVER, in the second clip, I do the same to a floater and credited for recovering a corpse (like the video you show above) (although I got no points for that).
So I guess when I asked, "Was this one of the many bugs in the original or a decision to change in OXC?" the answer was "bug in the original" ... or at the very least an inconsistency in the original. I didn't do enough tests to establish if there was a pattern. It's not mentioned in the
known bugs wiki page, so maybe we found a new 1994 XCOM bug.
I've fixed the message so it shows up before the debriefing, like in the original.
Don't know if it should be applied to New Battle mode though...
Just to clarify, I wasn't pushing for any kind of change or anything with my follow up questions. I was just curious about the point distribution differences I was observing (from vanilla to 1.0 to the Nightlies). I think the conclusion is that it was a bug in the original that carried to 1.0 and was corrected in the Nightlies. As far as the message placement, not a big deal either way, but I agree with your update as it makes more sense to tell you the live alien died and then give you 10 points for a corpse rather than give you 10 points for a corpse and then tell you the alien died.
PS - After playing OXC, even doing a few tests in the vanilla game was infuriating. Just the number of extra clicks you have to do (plus not being able to click a UFO to intercept it, etc) was driving me nuts. Makes me appreciate OXC all that much more.
