Slabs to Blocks: Biomes O' Plenty
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
NOTE FOR 1.20.x: Download polymorph because of conflict of recipes of what the BOP dev intended vs what I intended. NOTE FOR 1.20.1+: Don't expect for all slabs to have recipes, count yourself lucky if all of them do.
This preconfigured mod lets you craft your unused slabs from the Biomes O' Plenty mod back into their block variants, allowing you to not go through any config tabs to make the recipes yourself! All you need to do is simply place two slabs on top of each other in the crafting table!
