In addition to this, I’ve gone from 4-start Karma down time 1-star. Is there anyway to restore that karma back?

If you're using Google Chrome, I've found a fix: (It'll also work in other browsers, you'll just need to modify the instructions to find out where you can delete site data and cookies)
Go to chrome://settings/
Search settings for "cookies" and then click the highlighted content settings, and then cookies
then click "see all cookies and site data"
then where it says "search cookies" type catanuniverse
then click the delete on all of the search cookies things
Now, you'll be logged out and able to log back in, and it'll be in online mode
Just tested now, December 5th 2017, on the latest version of Google Chrome, and it works great.
@whuffo Good point, it does seem plausible that you get both of your players in the same game with a window of 1 or 2 min, possibly even less.
