M Daughters Minecraft Version:

Windows 7 64bit
64bit
Forge latest Version.


When Daughter tries to load worlds in SINGLE PLAYER mode, they get to Building Terrain screen then crash back to menu screen. Happens on all worlds.

Worlds load in Default mode just not in FORGE.


I have tried to do the following with no results.




Update to LWJGL 2.9.0

Forced Update on forge.

Removed all saved worlds in the saved worlds folder.

Problem started about 2 weeks ago...but i am just now finding out. Latest Crash report was from 12-14-13.

Thank you for any help. She loves this game and is heartbroken.

same thing here

********************************UPDATE************************************


Narrowed this down to the Dr. Zharks Mo Creature Mod.

Which includes:

Dr. Zharks Mo Creature Mod v6.0.1
GUIAPI-0.15.7-1.6.2
CusomMobSpawner 2.3.1

I tried to download a fresh version of all 3 of these with no luck. When I uninstall them the game worlds load fine.

So Now my Daughter is almost in Tears because she loves this mod so much...hoping someone can help me make her happy again. I really appreciate any help. THANKS.

********FIXED**************

Go To minecraft Config folder and Delete the corrupted MO Creatures folder and reload...a fresh copy of the folder should load and repair the mod.

Thanks all for allowing me to post in here and fix my own problem. But hope this helps someone else.
