anytime luca or freja are supposed to be on screen or talking i get an error message, it happens even after uninstalling and reinstalling.
That is probably the issue. If that's an old save-file from the times before we switched names - it will cause problems.
Sorry for the inconvenience :(
We can only suggest you to use the "skip to new content" option if you want to get straight to latest Threesome Scene without wasting time replaying the game.
