Hello! Just wanted to let you know, I attempted to run BoP v1957 and had crash at launch. Using forge 1804. Log enclosed: http://paste.ee/p/kzwF6 I down graded to BoP 1953 and have not been having any issues since. (That just happens to be the first version I downloaded. Didn't choose 1953 for any specific reason.) Hope this helps. If any further information would be helpful, please let me know and I will provide it ASAP!

You'll need to update Forge to use newer versions of the mod after 13ef3f8 (1954). If the game still crashes after updating Forge let me know, although I suspect if that is the case, it'll likely be because other mods you have installed will need updating on their ends also
