There is no event for Construct on the blueprint itself or its parent, i tried a few other events and nothing was listed for the normal ones.
Looking at the class in more detail; in the tutorial its a Abstract object blueprint class, which is like a root level blue print. And the actions such as quests themselves are added add as children of this class.
neither the parent or children are live elements, they are just functions if you like to trigger other things. I thought maybe i could cast a value from a widget UI to the tablet and then use the tablet to pass the information but that too seemed to fail with the same error, it just seems at some point the implemented method for this quest system is not the right one for complex quests.
I apricate you spending the time to respond however.
