Fast Furnaces

Additions:

• Aquamirae (1.21.1)
• Biomes O' Plenty (26.3)*
• Ecologics (26.3)*

Notes:

• Playing on 26.3 and above REQUIRES you to delete anything inside the 26.3 folder that does NOT relate to a mod you have installed. If you do not do this, Minecraft will refuse to load the data pack since it would contain unknown data. This is apparently the intended behavior, and was fixed in 26.3-snapshot-5. If you're playing on 26.2 or older, you can disregard this message as it does not apply to you. A text file containing the mod IDs and actual mod names is supplied for reference.
