Fun with AI patch.
Gameplay wise this patch mostly fixes AI issues, as we tried to make monsters slightly more aggressive and attack your buildings etc. When they are not able to attack you. It’s fun for the whole family! Also it's midsummer here in Sweden, so we celebrate by temporarily making the Maypole buildable.
