About this Mod

Worldgen Patches

This mod aims to patch some minor issues/quirks with world generation. Currently, this includes the following fixes:

The steep surface rule (which in vanilla gives Jagged Peaks stone faces) now affects all directions, not just the north and east-facing sides.
Snow layers correctly generate both below and on trees.
Beached shipwrecks no longer spawn at different heights and with different block palettes across chunk borders.
Igloos never generate a trapdoor if there is no basement.
