A bunch of new demos were released today, which is great, but it seems The Riftbreaker - Prologue has duplicate downloads. It says it has six parts, but parts 1-3 are named exactly the same as parts 4-6. Part 3 and part 6 are slightly different sizes though. Could it be one is 32-bit and named improperly or is this a case of a duplicate mistakenly posted? Thanks.

Found that this was asked already in this thread. No word on what the differences are between Parts 1-3 and Parts 4-6 yet, but I put a support ticket into GOG to find out.
