I acccidentially installed and started the GOTY edition after reinstalling my system. I think my savegames were synced on that moment and then I found out the GOTY doesn't load my old savegames.

I deinstalled the GOTY and installed my standard edition to find then out, the my savegames are gone. Could it be that there is an issue with the sync of the two editions? Can my savegames be restored somehow? 150h gone?

Please help.
