Hi Rob,

I updated my meta-ros by commit id 9a857af. by the way, I found there are 4 packages are missed than before, commit id 950bcc8.

Missed packages are :

aerostack2/as2-ign-gazebo-assets
aerostack2/as2-platform-ign-gazebo
dbw-ros/dataspeed-dbw-gateway
dbw-ros/dataspeed-dbw-msgs

Can you check and let me know whether it was intentional or not?
