Core Entity Registry Corruption

Server randomly rebooted. Now I have a core.entity_registry corruption

Opened file via nano and located the offending character. (A $ instead of a , between the “”)

Fixed file. Renamed the file from corrupted back to normal name.

Rebooted but all of my custom names for entities aren’t loading. Labels gone etc…

Any ideas why it doesn’t restore functionality when performing this action?

Maybe there’s more corruption in that file than just the one character. Can you restore that file from a backup by manually copying it using the Samba Add-On?
