Windows .exe FTB Crashes when loading new chunks.

This isn't all of the time, but quite rarely, I got out to explore my world and when some new chunks are loading, the FTB Pack gets a little laggy then just shuts down.

Save your saves and try a clean reinstall of Java and FTB

I'll try that and post something again if something else comes up. Thanks a lot

I fixed it by removing Optifine.
