I wouldn't leave a non-functional campaign and force everyone to tinker with it. I asked Hottabych to help, and I adjusted some bonuses. Look at the Master's campaign; he has 10 versions of maps with corrections. (This isn't bad; it's just that changes in files are a frequent occurrence, especially at the beginning when almost no one played and didn't test it much.)
But please tell me, I don't even know if this is a feature or not, but in the first campaign, the altars didn't give any experience (they do in the second)... and all the chests contain 100 coins and no experience at all... I doubt this is a feature.
P.S.
