Ok so I have a pretty good survival world that I have been playing on my Acer tablet while away on holidays. Since lag comes naturally when playing on a tablet/laptop, I downloaded Optifine to help. I was on my world and adjusting a whole lot of the Optifine settings when my Minecraft froze up and did a whole lot of weird stuff. I had to close Minecraft and restart my laptop. When I got back on Minecraft, my world (named Survival) was not in the single player worlds section! I restarted Minecraft, thinking it was a glitch and It still was not there. I went to the lastest.log and it came up with an error. Please help me get my world working again! I also tried the world without any mods and on my Mac but the same thing happened with the same error.
Mods being used:
Optifine 1.8.8
The 5Zig Mod v3.1.3 (for MC 1.8.8)
