I know, my code is still cruel, but before improving it, I want to know, why it doesnt work when I check it. No matter if I chose success1 or success: If I run the code, everything is fine, but checking it, it shows: TypeError: unhashable type: 'list', fortress_cannons, 80 , in the same test, which it has passed while running. Please help. ty for your help
