How to fix 'Head state missing' error in Bor node?

Hey folks, I just ran into an issue with my Bor node today. It's not syncing currently and I'm seeing the error: 'WARN [03-13|16:26:04.518] Head state missing, repairing'. I was previously synced up until today. I'm running a mainnet node, and I need to figure out how to fix this. Can someone please help?

You are running a mainnet node, right? If so, you should set the snapshot flag in /var/lib/bor/config.toml to false to fix this error. After changing it, make sure to restart the node.

Once you have successfully synced the node, don't forget to re-enable the snapshot flag back to true to maintain data integrity in future syncs.
