Forgive me if this is expected behavior, since I can duplicate it on my old node-red v1.1.3 and my new v3.0.2. The closest thing I could find to this is [Deploying the state machine node does not change its status](https://discourse.nodered.org/t/deploying-the-state-machine-node-does-not-change-its-status/22196), but the conversation was focusing more on moving the x y positions of the nodes, as opposed to cutting or adding wires between nodes.

flow:

```auto

```

If you look at the following screenshots, you will see that the node in the flow that had its output wire cut is the only node that does not get re-deployed when choosing **modified flows**. If this is to be considered a problem, then it is **not** specific to the function node. When testing on my custom nodes that had the output wire modified, the **close** event is not triggered for the individual node whose only change was an output wire being added or removed.

- deploy flow  

- inject timestamp to modify state  

- cut a wire (notice no blue dot to indicate change on any node)  

- re-deploy modified flows (notice which node did not get re-deployed)  

If the expectation that cutting a node's output wire is **not** modifying the node, then why would the other nodes in the flow get re-deployed other than the node that had it output wire cut?
