Hi the new Serializer is bug and break my project (no worry I use git so easy to revert). The boolean won’t get saved, for example the conditional transition that check a blackboard variable will not save the boolean value ($XXXX = false <– false can not be saved and will revert to true (default value) everytime I click play). And there are many weird behavior that I don’t really understand yet, i.e. a checkevent transition from AnyState will not move to the destination state even the eventdata was sent already. All these works fine in the previous version.
