i have made quite a large mod, when I added a new dimension the game just wouldn't start up anymore, when I removed the dimension it worked again, I tried to make dimension with default blocks and biomes after that but it still crashes.

Issue comments

I have loaded your mod and it worked. You are not using the right version of Minecraft Forge. MCreator 1.8.0 is made to work with Minecraft Forge 2705, so make sure you use this version.
