Im using version 1.9.2 of Steam and Rails and my 1.19.2 forge version is 43.2.14.

Whenever I load up the game with the mod in my mods folder, it says "mod has failed to load" and reason is "null"

The error message doesn't give us much. Please provide your full mod list and as much of the log as possible.

Having said that, I feel like this might have to do with a version mismatch, e.g. using Create 0.5.1 and Steam 'n' Rails 1.2.6 (for Create 0.5.0) in the same game. If so, please roll back to Create 0.5.0 until the next SnR update (#116).

If that is NOT the case, please reopen this issue with the error log.
