I don't mind cheating in my single player survival world. But I used kill all entities while filling a large chunk with air to get rid of the mobs. But I didn't know item frames are also entities. Why are item frames also entities? Minecraft can be so frustrating at times.
You see, I also had a 5x5 map wall on max zoom level (4/4).
So, can I use command blocks to get my filled in maps back?
