Finally found icebreaker and I got stuck to the third message to be collected after completing the quest for the icebreaker. Precisely where I have to multiply two numbers to get the result shown. After entering the first sequence of 4 numbers, I can no longer enter the other four. Today I lost 4 hours to try to complete it but nothing happened!! When fix it? In the link video, I had to do 16x18, but on the 18th (2358 for example) I couldn't did it. Someone can help me?
