Minecraft Forums

I have a heavily modded world that I've been playing on for a long time (well, maybe around 6 months). While I was playing the other night, I was experiencing a lot of lag, then crashed. I assumed it was from the lag since I was around a lot of mobs. I tried to reload it. The world loaded, but crashed seconds after. I tried this multiple times with the same result, though one time I was able to play for a bit longer.

In hindsight, I should have saved a copy of my world, but I didn't. Is there anything I can do to save my world? I'll post the crash log, if it helps at all. If knowing what mods I have would help I'd be fine with sharing. Any help would really be appreciated, I've put a lot of work into this world.

Ouch. Poor rabbit. Could you recommend a world edit program? I've never used one myself, so this will be interesting.
