It's no bug, I was just being silly again! Back when I left my review, i ended up brute-forcing the puzzle, because i couldn't find the ip and i wanted to get to the ending.
So now i reloaded the game, and took another look, just in case there was abug. Turns out I had solved all the Kaskas, including the Ip one, i just missed that one of the 3 had the ip in it and then must have miscounted.
I blame the massive heatwave! And also thank you for making such an awesome game, i had so much fun with it
