Hey all, after a reinstall it seems that my hall of fame, as well as cloud saves, were wiped clean. 2k account is linked and everything. Anyone else have this issue in the past?

No, just installed Steam and Civ on a new SSD and still got hall of fame.
I didn't uninstall game when I was using my old HDD though.

If you moved game save directories or if you have some type of backup/version control on your PC, you can just replace or restore the HallofFame.sqlite file in the current save directory. New Windows versions love to direct you to onedrive directories that look like your old directories , but they aren't - they are in a different part of the directory tree. A Blank HallofFame.sqlite file is about 88k. For a random reference, mine is 7.75 MB - so you will probably know if you come across a "good" version.
