Cerbo GX Relay state change after firmware upgrade via VRM

Hi,

I use a relay output on the Cerbo GX to control my Off Grid pure sine wave inverter based on SoC coming from a JK BMS, with inverted logic. So 'generator Start' means my inverter is shut down due to low state of charge and after a preset higher SoC the Generator Stops, so my inverter starts.

After I have upgraded my Cerbo GX today via VRM I noticed that while the Generator was Running before the upgrade (so my inverter was OFF), the Generator has Stopped (my inverter started up, consuming idle power) after the upgrade.

Is it a known issue?

Should/could Cerbo GX keep its Relay state when performing a firmware upgrade?

I mean in my situation it was not critical but in a more sophisticated system it could have been.
