Just started using forge on hamachi world always restarts? (Read)

[PJDUNN]

Im new to forge and mods and minecraft pc. The world is there and playable for a few hours and I always do /save-all and it still doesnt change anything. I woke up today to use it and it said unable to find spawn biome and made a completely made a new world? Why does it do this. How do I fix it so the world I make doesnt get deleted or removed?

You posed in the wrong section and possibly the wrong forum (Try minecraftforum.net)... But anyways

 

Unless the game's auto-save is disabled, which it should not have been, you don't need to run the /save-all commend. As for the spawn biome not being found... I'm not too sure what may have caused that to happen, you may have gotten unlucky and your world got corrupted, make a new world and check if the same problem reoccurs.
