Peices of Scenery missing

[firefly]

Flying around Boston I found this hole in the scenery.

I have this problem around KSFO area also. I can still land on the parts where there is no scenery.

This problem was not there a few days ago.

I did not update Flightgear.

There are no errors in the console.

The problem is still there with different rendering and shader and texture options.

I am using Flightgear version 3.3~11834

Maybe it was a terrasync error, it seems resolved now.
