Behavior Tree crash when adding Blackboard Decorator
Hi you all!
I'm using the awesome Behavior Tree editor and I've encountered an error that makes the UE4 Editor crash. This happens every time when I add a Blackboard decorator in a Selector Node and click on it to inspect values.
I've tried to replicate this in other projects (ShooterGame i.e.) and the Blackboard Decorator was added correctly.
Thanks in advance.
I've found similar situation [version 4.1]. This occurs when you add decorator "Does Path Exists", then FBlackboardKeySelector::CacheSelectedKey method proceeds with SelectedKeyId == 255 even if bNoneIsAllowedValue is false. In this situation, SelectedKeyName is "SelfActor", which doesn't exist in blackboard keys collection :)
It's possible that having "SelfActor" in many cases is mandatory. Let's just wait for answer from Staff. Cheers!
I have had this exact same issue.

This issue happens for me in 4.4, with a brand new BehaviourTree and BlackboardData. Even with the SelfActor key first in the list, which was already added by default when I created the BlackboardData.
