Great map, but it’s quite challenging for a beginner. I completed it in 35 months, and towards the end, there was an overflow of money, and it went from some large amount to -2147483647. I could only defeat the thousands of dragons with the help of vampires. And I have a question: for some reason, I can’t equip certain (usually cool) artifacts, swords, and helmets. I select them, but the slot where to put them isn’t highlighted. What am I doing wrong?
