UPDATES:
- Now updated to 1.0.7:
- Java 1.20.1 for Forge, NeoForge and Fabric
- Java 1.21.4 for NeoForge, Fabric and Quilt!
- Better Beds Reforged has been removed in all versions that contain EnlightenedBlockEntities or EnhancedBlockEntities as it conflicts with those mods, causing beds to render incorrectly.
- VanillaIcecreamFix has been updated and is now compatible with Applied Energistics 2, and you are now free to add AE2 to any instance of Minecraft Optimus of version 1.0.3 or later.
Coming soon:
- versions for Java 1.21.6 will be released as soon as the mods involved are updated. This will then supercede the Java 1.21.4 versions.
Known incompatibilites:
