I have had an infinite peaceful survival world for a few weeks now. I opened my game today and immediately "fell off" the edge of my world. I exited the game and assumed it would go away if I rejoin the world. I spawned where the original world spawn is and had to travel all the way back to the coordinates of my base but nothing was resolved. The entire area of my house (mine, farms, gardens, etc) is completely gone and I got the messages that my dog and cat fell out of the world. I have tired to restart my phone, exit the game but nothing is working. The surrounding areas seem to be unaffected, it appears that only the places I've built are disappearing.
