The Bug is that Minecraft can create worlds without any problem without the mod but when I install Waystones it doesnt create the world and it doesnt even give me an error, just stays there doing nothing, I do have multiple mods but i did uninstall all mods and let only waystones and did not let me create the world.
I do have other mods but the mod itself giving me problem is Waystone

I, too have this same problem

need latest.log
