I have just finished this scenario and am unsure of the success of my ending. I closed the fourth and final portal using all four "key" items and got a brief onscreen text description which didn't end with the usual words "The investigation is complete". My closing narrative screen (which I can't attach as the files too big) describes me scrambling out of the house as the floors shake then all becomes quiet and calm as I exit , the dread and fear eases away etc. Looking back at an empty building awaiting its next occupants. This sounds like a successful ending to me but was my investigation incomplete ? Incidentally , Officer Tetsuo Mori was still alive. I know there are different outcomes for scenarios but this was my first play through of this one as I have just bought the Beyond The Threshold expansion. Thanks.

Warning, another Spoiler here ; I guess we can probably call this scenario notorious for this soon.
This is from the last time we played:

Spoiler: "We were playing "Gates of Silverwood Manor" ,
figured out what we needed to do pretty quickly, but failed
at one point.

Then we had to do something extra and thanks to the
"special" feature of the scenario, we didn't all make it
to the final room in time.

This triggered a map change that confronted us
with a boss fight, which we won, so far so good...

However, now the game told us that we started investigating
a new case, which was actually the same as the last one,
but we couldn't remember anything that had happened
before.

That was the ending."
