The editor crashes if a BT is changed while its Blackboard has an Object type key with its BaseClass set to None (null). There is no warning or log alerting the user that setting the BaseClass to None is not supported/advised.
Expected Result: The node moves with the cursor as normal.
Actual Result: The editor will crash with a callstack containing UBlackboardKeyType_Object::IsAllowedByFilter
