Java Edition:Mined Structure Void Statistic
In a two previous April Fools' snapshots, it has been possible to obtain a Mined Structure Void Statistic by mining structure void blocks.
Obtaining
20w14∞
In the April Fools' update, 20w14∞, structure voids generated randomly in the "skygrid" dimension. These structure voids could be instantly mined by the player. Although they couldn't drop structure voids, they could leave the player with the "mined" statistic for structure voids, which is usually impossible because there are none in the world. This statistic will stay with the player, even if they update. This statistic could be anywhere from 0 to 2147483647.[1]
22w13oneBlockAtATime
In the April Fools' update, 22w13oneBlockAtATime, endermen could place down structure voids, which can be mined. Players could also place structure voids which you can obtain as an item in this snapshot. To gain the statistic you have to go to a version other than 22w13oneBlockAtATime.
