Modpack Crashes On Start

[Harjas2102]

Hey. I'm having a problem when starting my modpack. It will be at the mojang screen and loading mods, but then just crash and go back to the technic launcher.

• I was able to successfully launch your pack. Try removing it from your launcher and re-adding it. Make sure you are incrementing the pack version number any time you alter your pack data or metadata.
• You have Biome ID conflicts. Check your logs.
• Your pack is insanely huge and uses a tremendous amount of RAM to start a SSP world. I wasn't able to successfully enter the new world until I increased my Launcher RAM allocation to 5G. If your system has less than 10G of RAM it is going to struggle with this pack.
