The .jar File Deprivation

The .jar File Deprivation is a colloquial term, coined by Elder josephandjake, describing an event that occurs when Minecraft is updated. When Mojang push their updated .jar files to the general public, many Minecraft players, experienced and inexperienced alike, forget to copy their old .jar files in the haste to trial new features. This generally causes a minor decline in server activity, and in some cases, calls for special action to be taken.
