Missing files should be ignored and we carry on.

Unfortunately terraSync currently starts syncing below the level of the layer directories - it never actually syncs 'http://dream.t3r.de/fgscenery/Buildings/.dirindex’, but rather looks for a sub-dir beneath that.

The same thing would happen for an Objects or Terrain dir, there is nothing special about the new layers here, I believe. (Stuart, unless you have changed that?)

(This is also why terrasync makes rather too many .dirIndex poll requests on startup, since it doesn't just check the top level indices)

I have local patches to improve this, but I have not been able to test them out to my satisfaction, but I can share the change if people are interested.

Kind regards,
James
