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

The ice barn clue in row 10 could not be visited twice, as the horizontal crossing would violate the Liar restriction, as it would be a room entry of length 1.

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.

Thanks
