I played this mod, and I sudenly get a lag. Lag lasted about 5 minutes, so I've turned off my computer and turn on again. When I opened Minecraft, my world missed on worldlist. But when I looked to saves, there was a folder for this world. Can somebody help me please? Thank you.

Also excuse me my english, I'm from Czech Republic.
