Yep, 1.3 and 1.4 are almost the same. The old Build is either 1.1 or 1.2, i have forgotten (that´s what happens when you repack old demos and forgot to proberly name them).
The Cutscene Map is still up on the original Itchio page https://arturlaczkowski.itch.io/silenthillsmap so No don´t need to reupload yet... But I have Copies just in case it get´s deleted in the Future.
