That's correct. I hadn't tried making all of the add-ons required, after seeing the above post I went and changed those settings in UA and sure enough - All of the Add-ons came down as they were supposed to.
If the addons are optional and are checked, UU will uncheck them after synchronizing twice.
I have attached another debug log - This one synchronized once after making all add-ons required (all were successfully downloaded). I have made no other changes to UU or UA since my last post.
Thanks!
Note: I am trying this on both my desktop and laptop installs - I get consistent results from both.
