My realm did not save after server maintenance!!

OK, so when I was playing Minecraft on my realm, I got a notice in the chat window that the server would be closed in 5 minutes. 5 minutes later, and I was kicked (Which I expected). I got back on today, only to find that the realm had NOT saved our work from about 45 minutes until the server close. Can you please try not to let this happen again?? When the server was closed I was the only one currently playing.

Thanks!!
