It's also generating significantly less in Dark Oak forests

Seems to be due to the changes to PlaceOnGroundDecorator.placeBlockAt in 25w03a. In 25w03a, the place_on_ground tree decorator placed leaf litters one block lower than before. It causes the decorator to not find a valid pos to place blocks in most cases.
