EDIT: *sigh* As soon as I go back to the game, I figure out the problem. Is there a way to delete threads...?
So I got bored and started making a dungeon thingy. Place an egg, spawns a dungeon. It's not randomized however, and I hit a problem in my first three command blocks.
You can see the setup and the commands in the picture, and here is my problem.
It gets to the second command block, but doesn't clone the structure like the third command block says to do. However, if I execute the clone command alone in chat, without the execute, it will clone. What's the problem?
