I decided to build my house on the higher section of the farm, so I thought it would be a good idea to move my tent over as well. Once I had moved the tent I was unable to place the sleeping bag back inside it and poor little mini-me has to sleep in the rain :(
I also did this but took it a step further. When I was building the house I put the plan for the bed inside and deleted the sleeping bag before I finished the bed. I then later realized that I couldn't sleep anymore and all the shops were closed so I couldn't get the materials to finish the bed. Since the day doesn't progress unless you sleep I was stuck and had to start the day over lol
You need to be inside the tent or house, then open the drone app and move the sleeping bag inside. Just figured this out.
