Warning
Pretty ugly code ahead.
It's quite embarrassing but someone might still use it even if it's broken.
There is most likely no fix coming, use at own risk.
AdvancedZones is a advanced and more complex plugin than others. It gives you much more possibilities and freedom in doing what you want. You can create Zones in every possible shape and size. Each zone can be customized for itself.
