Observed Result

• Using dirt to fill in the area where pale and dark oak logs will grow shifts the Y coordinates and creates logs in the sky.
• This may have happened in Survival, but a superflat with a negative y-coordinate is probably easier to reproduce.
• In addition to the logs, the leaves also seem to be generated at coordinates that are offset from the logs.

Expected Result

• Ensure that there is no misalignment of logs and leaves, as this will break light-related gimmicks such as daylight detectors.
  If generation is inhibited by dirt, it is hoped that generation will be cancelled.
