I cant see how that is not on topic, since it does what you want. If you want it in another way, you will have to search for a diff that can patch the client accordingly.
What's the point though @@nuna? If there were two servers and you wanted one of them auto-selected, you'd never be able to choose the other one... logically this isn't something anyone would want...
So the point is that if you setup a server with say the server is uae / langtype 19. Only the second server will be applied with the right to left chat. The first server will not have this. Not sure how to get the 1st server to have that behavior.
