Using Ambient sounds 6.2.3 (though this happened with 6.2.2 too), along with creative core 2.14.7. Any time I try to play on or create a new world, the game will crash as soon as i am about to join said world. crash only happens with Ambient Sounds installed, unsure if its a mod conflict or not, but in my testing I have not found any specific culprits.

That is a very weird crash. I have tested it myself and it works fine. Maybe it is a conflict with another mod?

I'm having the same issue as well.

Here's someone else who's having the same problem, but in my case I only have mods like Create, Sophisticated "series", Supplementaries, etc. And I should add that I haven't added any biome generation mods.
