shutters version 2.0.2-1.20.1
mc 1.20.1
forge version 47.2.20

so all the shutters open and close like they are supposed to except for the iron and netherite versions. can we please get this fixed?

The iron and the netherite shutters can just be opened with redstone as it is in vanila. We will try change the behavior to be more closer to the supplementries behavior.
