UPDATE: We believe we have resolved the issue. Fortunately, this affected such a small number of people, we will not need to restart or cancel this war. There is no need to send in a support ticket, as we are aware of which players have been affected by this issue.

There is a known issue with version 22 which is causing some players to lose connection during war battles, resulting in 0 points.  

We are currently investigating this issue here and will try to get it resolved as soon as we can. Unfortunately, we may need to cancel or restart the current war. 

When we have more information we will update this article.

Our apologies for the inconvenience caused by this issue.
