Wow that’s a good score from my experience. But i dont get the discrepancy thing. Did you win or lose? You said you lost but you also got a victory screen?
Yes, I lost my castle, which gave me some kind of defeat screen with a score, but after I got a victory screen with a different score. After a few screens (an epilogue screen, a thank you screen, etc), I was back at the main menu. I chose to reload, replayed the game from day 95 onward and successfully protected my castle, after which I also got a victory screen.
