For a few days now I have tried running a flight plan, as an example see the screen shot.

As you can see the weather is not being considered in the flight plan for fuel planning. I noticed this ever since the most recent site update occurred. When will this be fixed?

You most likely accidentally disabled “Detailed Navlog”:

Once re-enabled, make sure to click “Save Defaults” so it also applies to new flights you create from then on.

Regards,
