I grew a 2x2 Spruce tree in a Plains Biome and the Podzol that generates as a new set of Grass spawned 2 blocks above the regular Grass Blocks and 1 block above the Grass, with the Tree going through the layer of podzol.

I started a world on 2/8/26 and a few hours into the Survival game I encountered a bug whilst trying to grow a 2x2 Spruce Tree, The podzol that usually spawns below the tree in place of the Grass before it was spawned 2 blocks above the Plains natural X-Level. This bug I had never seen. I don't know if it was my software or just my game but I’d like to uncover the secrets of this particular bug.
