started last night, when you go to messages, you can only see the left half. It is the same today.

For which country are you experiencing this? We didn't change any code overnight so the problem is likely the specific message's content.

I checked FFA. server messages are normal in that server, I can see everything is normal there, the problem seem to be in Alliances only.

Are you seeing something like this? https://imgur.com/a/Ym4IG9L

This should be fixed now. Can you confirm that the problem is resolved?
