So I was creating a gate with command blocks on a world that my friend and I share. As I was building this gate I ran into a problem which was the fact it gave me an error code that didn't make sense which was "Cannot place blocks outside of the world" but the place I was placing the blocks with the /fill command were only about 40 blocks away from me and my friend was sitting next to where I was placing the blocks. After that I went right next to it made sure I had the right coordinates and typed the command out in the chat instead of in the command block and I got the exact same outcome. I attempted this about 20 times switching back and forth between the chat and a command block. Please fix this.
