Hello everyone, I recently discovered a huge hole that took apart a house I made. this hole wasn't here before when I made the world. unlike some posts ive seen this one is interactive. I can go in it and place blocks in it. It goes all the way down and has a 3 grass block bottom. This is on regular Minecraft 1.12 singleplayer. I'm not sure how it happened but it might be because I went on the same world with 1.5.2. I have no idea what to do, I've tried so many tutorials and they don't work. Please help, and let me know if there is any way i can fix this. if you need any more information on it please ask. Thank you.

Other than using a backup there is nothing else you can do.
