SaveSync now works properly with Windrose. The new save path introduced in a recent patch by the Windrose developers is now fully supported.
Instructions for use:
Launch Windrose before opening SaveSync so that the game migrates the save to the new path, then open SaveSync.
Important Note:
If you previously played Windrose while SaveSync was not working and now you see a "Activate" button, do not click it, as doing so may revert progress. Instead, delete that save from SaveSync and re-add it by clicking the "+ Save" button.
If you already clicked "Activate" and your save reverted to old progress, check:
%USERPROFILE%/AppData/Local/R5/Saved/SaveProfiles/{64BitSteamID}/RocksDB_v2_Backups_ss/
SaveSync moves a backup before activating, so you can copy that backup back to "RocksDB_v2_Backups", start the game, and recover your progress.
