Minecraft Forums

I have been working on a superflat map in minecraft on creative mode and i have gotten near success of finishing this map but after the third day on trying to load the map again i got the loading screen then i got "shutting down internal server" I have tried uninstalling minecraft and reinstalling it but nothing seems to happen. I am running Version 1.4.6 with the 1.4.6 forge mod along with SCPCraft mod. The "Shutting down internal server" always seems to happen on my specific save i mentioned.


Here is what i get as a Crash Report:
