Recently I've created a mob spawner in a mystcraft age obviously for perfect spawn rates. Then I put a mystcraft portal at the bottom of the trap to teleport mobs back to the overworld therefore I never hit the spawn cap in the age. But as soon as I changed from peaceful to easy and the first mob hit the portal FTB crashed and continues to crash when I load the world. If anyone knows why or a way to fix it that would be great.
The crash report is attached, Thank You for your time.
