Have you made the changes we discussed on that other post?
InitializePropertiesBinding, is called only from in Blackboard Awake (and by extend GlobalBlacboardAwake since it calls base.Awake() and it does not matter whether or not the GlobalBlackboard has been added in the allGlobals list. PropertyBindings will always be called in awake, since it is a runtime thing too, while the allGlobals is simply a list for faster accessing the GlobaBlackboards.
Maybe there is something else going on here? Can you please provide a way to reproduce the error you are facing here?
If you want me to send you the current versions of Blackboard and GlobalBlackboard, so that we ensure we are on the same page, please let me know.
