World save error

So I'm back to playing Minecraft. Me and my sister decided we are going to do a survival game, we used Minecraft 1.8.9 with no mods and everything was great, until the next day when I opened the world again and around 3 blocks length at the end of my house was like completely gone, including my only chest with my stuff in it.

I then rebuilt it and thought nothing of it and we continued to play, we played for 12 hours so we got a lot of stuff done. Now I've just opened the game this morning and a similar thing has happened again. For example we built a barn and the corner of it is missing and in several places that were removed.

The original part we cleared has come back.There were also other random things that disappeared, stuff like red stone lanterns as lighting, my furnaces and other decorative things i added to my house.

I have no idea why this is happening, I have mods downloaded on a Minecraft 1.7.10 profile that I've had for years and Minecraft 1.8.9 optifine that was installed recently but I'm not sure if that would effect it, other than that there is absolutely no other mods installed and this has never happened before on previous servers.
