Previously, the save files were in: C:\Users\[user]\AppData\LocalLow\Tactical Adventures\Solasta\Save Files
Now they are in (compare bold): C:\Users\Russell\AppData\LocalLow\Tactical Adventures\Solasta\Saves
This may be deliberate due to the old save file invalidation, but it may also be related to the save file issues in the other threads.
I've been having no luck getting the game to recognize that I have saves or previous characters at all, and I tracked down the location and like you said, there were two folders and all my old saves were in \savefiles. I tried cutting and pasting them over in \saves, and now the game recognizes that saves exist (the continue and load game options are no longer greyed out) but it won't display any of the saves, or any of my old characters, which seem to still be in the \characters folder.
Anyone had more luck with this?
