Minecraft log:https://mclo.gs/6A7uptF
I have checked all mods and the version of forge ,and found the problem cause by this mod
Sometimes ,it cause crash while join to world
But in other times,it cause crash while loading
Sometimes ,if crash while join to world ,it may also cause resorce pack failed to load

I created a modpack and encountered exactly the same problem when starting the game. latest.log (https://mclo.gs/zAjtamj) ends with just launch parameters, and there is no crash reports
I remove the mod from the folder and without Steam 'n' Rails everything works fine
