Copying and pasting behavior tree nodes reverses the order of any decorators on the node.

Found in 4.11.2 binary. Reproduced in 4.12 Preview 4 binary.


Yes. This does not occur in 4.10.4 following the same repro steps.

Steps to Reproduce

1. Open the editor
2. Create a new Behavior Tree
3. Create a Sequence Node
4. Add a Blackboard Decorator & a Cooldown Decorator
5. Copy the Sequence Node (CTRL+C)
6. Paste the Sequence Node (CTRL+V)

Result: The Cooldown and Blackboard Decorators are in reverse position.
