Server broke my game

When me and my brother found this server on YouTube we played on it for about 3 days and today me and my brother where going to go play in our theme park. When I looked EVERYTHING was gone. All of the terrecotta and concrete and dyed beds were GONE. AND when my brother went in his world to check if things were fine beacause he just deleted the server. And he went to go check on one of his creations in the item frame and it was a glitchy mess. So please please please please plz plz plz plz plz plz plz plz plz plz PLEASE fix this. If you could me and my brother would be the 2 happiest people in the whole galaxy. Please fix it Mojang. Thnx
