I got another solution, could anyone check it, please? It's only different in the middle sector, starting in row 8 (key C): 213312; row 9: 11211222; row 10: 112341 and the ice-barn-clues in row 8 and 10 are visited twice. Thx
Oh yeah, I got exactly the same mistake... Noticing that this particular ice barn crossing is forbidden by liar rule was pretty tricky to me, that was the mistake I was searching 20 minutes for and it would definitely simplify the process of solving had I noticed it earlier.
