howdy all, I have a problem with save_when: modified on nx-os. It seems like this is not working idempotently on Cisco Nexus devices N5k, N6k and fails on N7k (with a timeout), but seemingly works for N9k. The module is always flagging things as changed even when the config is already saved. save_when: modified is only supposed to save if there are uncommitted changes? I looked for a bug on git but was not able to find one. I'm running ansible 2.6.2.

my simple task

---

- name: NX-OS Save Config (nx-os config)

nxos_config:

provider: "{{ prov }}"

save_when: modified

I even did a copy run start on this device before I ran this task
