Save, cloud, and technical support

Direct answer

Make a local backup before troubleshooting a save. The companion does not upload save files or replace the game’s official support and bug-report channels.

Next step

Copy the save before testing a fix, keep the game version and platform with your notes, and use the official feedback or bug-report channel for a reproducible issue. Use the local save-import tool only when you are comfortable keeping all parsing in your browser.
