 * Population tables currently not modifiable via XML - this is a workaround to update the population tables at run-time.
 *
 * The [WantLoadBlueprint] tag and a corresponding object blueprint cause the LoadBlueprint method to run on mod load,
 * and from there we dynamically add our grenades to the Explosives lists. This will allow them to be sold by Grenadiers
 * and used in any other part of the game where the Explosives 1-3 population tables are used.
