Dupe of MC-38527

The view distance has been set to an invalid value that isn't supported in 1.7.10. There are instructions in that post to resolve this.

Downgrading is not, was never and will never be officially supported.

Use a seperate instance for your Snapshots, like you are told to when activating Snapshots.
