They added a few (unnecessary) visual gimmicks like exploding numbers, being able to tumble your own pieces around (board physics option), and some other "cute" bells and whistles. I wish they would have just concentrated on fixing the things that were broken and implementing improvements people actually asked for.
I have had a similar issue with the knight demotion.
2nd level knight was used to break someone's longest road. After it was moved to that intersection and fed again it demoted to 1st level knight... but only visually on the board. It was still showing as strong knight in the knight count for that player and against the barbarians though. (screenshot here: https://i.imgur.com/aOFdS8a.jpg )
During the C&K flash season, with some freezes, 2 losses were counted afterwards but my 2 wins and one 2nd place were not counted. After 5 games my ELO should be 1009 but I’m stuck 988. This completely ruins it. I wrote an email to support with expectation they fix during season. If not, I see no point in further playing the game anymore, the fun is gone if you only get punished and not rewarded.
@blackninja If you get the message "no connection to the internet" please try to log out manually and back in again. This might sound a bit weird but you will force the App to create a new connection to our servers by doing so.
If you are using an Android device you can also try to clear the App Cache on your device for Catan Universe.
If using an iOs device please try to do that by uninstalling and downloading the App again.
As nasenstein already mentioned, please contact our support team with further details on your system. As we can see from the screenshot, a shader error points to a graphics card or driver issue. Are you using a card according to the minimum system requirements with up-to-date drivers?
