Hello, So I downloaded forge 10.13.4.1614 and 10.13.4.1558 for 1.7.10 and this problem is with both of them. When I enter my singleplayer world, which is for 1.7.10, it says it's creating the world, followed by 'shutting down internal server'. Minecraft doesn't crash, it freezes. It does crash after a few mins of waiting though. The superheroes mod is the only one in the mods folder. Could anyone help me? The file name of the mod is Superheroes-1.7.10-1.0.13.jar. In case I have the wrong file.
