I'm aware this is a beta. I'm supporting the effort by contributing by helping to test it.
Vanilla MC loads fine, but when using Forge, it results in a hard crash every time on attempting to join a world (doesn't matter if it's offline new world, or joining a server, still consistently crashes every time). It crashes with this error:
The game crashed whilst starting integrated server
Error: java.lang.NoSuchMethodError: net.minecraft.util.ResourceLocation.compareNamespaced(Lnet/minecraft/util/ResourceLocation;)I
Exit Code: -1
Log is included. Let me know if I should open a new issue over on Github for Forge.
