[1.9.4] Property clash I think?

Hey guys. Out of the frying pan and into the fire! I fixed the issue with the hash code thanks to Choonster and diesieben and now I get this:

java.lang.IllegalArgumentException: Cannot set property PropertyInteger{name=age, clazz=class java.lang.Integer, values=[0, 1, 2, 3, 4, 5, 6, 7]} as it does not exist in BlockStateContainer{block=null, properties=[stage]}
