For anyone out of the loop, 1.14 had some changes to the background of how minecraft works/processes commands, leading us to have to go through most (if not all) the science areas and items and update them to the new formatting.

Because of this, we took the opportunity to re-balance and improve on many of the past items around the areas, especially earlier items.

The following are all items changed during this update; if you owned any of these items prior to 1.14, please visit the Science Workshop in the basement of the Post Office (at the Creeper Citadel) and have your items updated!
