EtFuturum Requiem introduced the “Frost Walker” Enchantment, which seems to work with vanilla Water Blocks but not GT6 biome-specific Water Blocks. Specifically, neither “River Water” nor “Sea Water” seem to work.
Don’t know if such compat can be added from your side though.
Talking about that, when the Water gets frosted and melted again, will it “remember” which kind of Water it was before?
Since making separate Ice Blocks for each kind of Water Block doesn’ sound like an easy way… Or perhaps you’ll store that info into the metadata or NBT?
that can only happen when the pipe drains to a complete emptiness. Also i could just make an exemption for water blocks next to Fluid Handling TileEntities.
