Automatic rollback not working

[Charlie]

Had an issue last night where i accidentally changed the timer settings on a backhaul link causing it to turn off the backhaul radio. This stopped remote access to the site.
I expected that the web browser would not be able to verify the configuration within the 60 second window so the netonix would revert back to the previous configuration but it didnt happen - I had to drive out to the site this morning and can confirm it had permanently saved the settings.

Is this possibly a software bug where power/timer config changes dont roll back after 60 seconds if the web browser doesnt reconnect to the GUI?

The firmware is 1.4.7 but i cant see anything in the change log for newer versions relating to it.
(Will update firmware anyway)

Can anyone else reproduce this?
