A little while ago, I checked out Galacticraft for 1.6.1, which requires another .jar file called MicdoodleCore-1.6.1-a0.1.37.449.jar. I made the mistake of using it on a map that I love dearly and have spent several hundred hours working on in creative, of which I do not have any back ups of. I created the rocket, with the launch pad and everything. It took off, and was working. I chose the moon to land on, once I landed, I decided to use the moon buggy. When I clicked the ground to place it, Minecraft closed. I have tried opening it several times but it does the same thing, I've deleted both the Galacticraft jar and the MicdoodleCore jar from my mods folder, and it still does the same thing. It gave me no crash report at all, it just closed, so I had to look into my .minecraft folder.
This was the crash report

I have Forge installed, as well as
-Damage Indicators v2.8.2.0
-Rei's Minimap v3.4
Please help me get my map back, I've spent too much time on it to just delete it and forget about it.
#2: Why are you using an experimental 1.6 build on a "map you love dearly"
#3: Updating the mod fixes this problem.
