4.9.2 Behavior Tree is not running from quick start instructions

I ran through all the steps in the Behavior Tree Quick Start Guide and my behavior tree isn’t running. I’ve gone over all the blueprints and events MANY times, and everything matches what is in the docs. (And I’ve even used the “Is At Location” instead of the “Reached Move Goal” as it’s listed in the docs) but when I run it, the BT never goes past ROOT. Has anyone else had problems with this? Are there other changes that need to be made to be compatible with 4.9.2? Been pulling my hair out trying to figure this out. Been over all the graphs and functions, and I did find a couple errors of my own, but those are all corrected now, everything has been recompiled many times, but I’m still not getting the behavior tree to run.
