Q: I've turned on recording, placed some bricks, stopped, and when I press play, nothing happens! What do I do?
A: Its simple:
1. Put down a ghost,
2. Start the recording,
3. Place your bricks without changing the camera direction,
4. Stop the recording,
5. Delete the recorded blocks if desired,
6. Place down a ghost (but don't press enter!),
7. Press your play hotkey and watch it build itself, *
Thats it! If you have any more questions on macro building or anything, just ask.
* Make sure you have a ghost or else nothing will happen.
