Forge Mod Loader detected that the backup level.dat is being used.Launcher Version:
Details of the issue:
I launched the pack as I normally do on my Mac, and loaded my single player world. A screen came up saying that "Forge Mod Loader detected that the backup level.dat is being used. This may happen due to a bug or corruption, continuing can damage your world beyond repair or lose data/progress. It's recommended to create a world backup before continuing." Below it are two buttons labeled Yes and No. Clicking Yes takes me to a loading screen and then displays the same message with the same buttons. Clicking No takes me back to the screen where you can choose multiplayer or singleplayer. I tried to create a backup world, but couldn't find the saves files like in unmodded Minecraft. What should I do?
