IMPORTANT NOTE: Be sure you are in a full height tunnel (at least 2 block high) before saving or exiting your world if you choose to use the transparency bug for finding Aluminum Oxide. If you save or close the game while your head is still in the block above you, you may be stuck in a transparent underground permanently. This doesn't happen all the time, but one time is once too many :(
