This is likely due to your Internet connection dropping while playing the game. Not to worry though as it can be resolved as follows:
  1. Check that your device has a fast and stable internet connection here. The minimum recommended download speed is 3 Mbps, upload speed is 1 Mbps and a ping rate must be under 150 ms.
  2. If you're using mobile internet, try switching to Wi-Fi.
  3. Turn your device off and on.
If you are connected to Facebook in the game, clearing the application data should fix it:
  1. Open Settings
  2. Scroll down and tap on Apps
  3. Search for "Delicious Bed & Breakfast" and tap on it
  4. Tap on Storage
  5. Tap on "Clear data"
  6. Force close and reload the game before reconnecting to Facebook in the game
