ignore these message, config should be updated sucessfully regardless

I checked. it reset my entire config

If you have backups you just need to role back to 2.6.0 and re-add the data and config files
It's what I had to do to get things working properly again

To find your backups and fix FurnaceUpgrades
- File Manager
- Backups (If you have restarts)
- Select file that is needed (This should be dated)
- Download file
- Extract and replace new files with old (Data, config then plugin in this order)
- o.reload FurnaceUpgrades
