This is a worldgen patching mod made to safely remove mods in between modpack versions, allowing worlds to be upgraded and prevent important blocks from being deleted.

It was made for the Better MC [FORGE] BMC4 and Better MC [NEOFORGE] BMC5 modpacks.

Can I use this in my own modpack?

It's not recommended, but you can. This mod isn't very configurable. It's mostly on Curseforge for convenience and easy distribution within modpacks.

What is remapped?

0.1.0: (DTKUpd -> Pale Garden and Creaking)

DTK Updates' Pale Garden Biome, all Pale logs, planks/wood decorations, leaves, moss, and creaking hearts are remapped 1:1. Pale Garden and Creaking does not have any stripped wood variants at the moment, so these are remapped to standard logs.
DTK's "super birch biom" is remapped to a standard birch forest, and its "green birch leaves" -> vanilla birch leaves. All other strange completely unrelated block inclusions, like vanilla vertical slab variants and duplicates of existing vanilla blocks, are not remapped, and so will be removed entirely.
Entities are not remapped - these will be removed.

**0.2.0: (Pale Garden and Creaking -> Vanilla Backport)

All of the above mentioned Pale Garden objects are remapped again to Vanilla Backport biomes and blocks.
A patch is added for a breaking change within Oh the Biomes We've Gone

0.3.0 (Planned):
