NoSuchMethodError when there is a method

[Unum]

This is my mod- I made the jar and ran it through the normal launcher.

See the crash reports below- I am using release 1.12, forge 14.23.2.2611. It somehow makes a NoSuchMethodError when it starts, but 

public static void registerTileEntity(Class<? extends TileEntity> tileEntityClass, ResourceLocation key)
{
    registerTileEntity(tileEntityClass, key.toString());
}

there is a method in GameRegistry with the required arguments. I am not using the deprecated version.

GameRegistry.registerTileEntity(TileEntityTowerMobSpawner.class,
    new ResourceLocation(VillageBattles.MOD_ID,
        "TETowerMobSpawner"));

here's the code I used. It's in preInit.
