Before, it was too easy to sythesize sapphires for hydro generators and
the water-breathing armor, and huge amounts of chromium could be made by
grinding rubies and splitting the dust in a centrifuge.
Now they both require 5 dust samples per gem (up from 4), and the
corundum recipies are no longer symmetrical. Ruby dust takes an
additional alumina sample to create (up from 3) and does not return
chromium when separated. Sapphire dust takes 2 iron samples (up from 1,
alumina req is still 3), but only returns 1. These values are outlined
in the source files so you can change them back fairly easily.
Thanks to HybridDog for pointing this out. This update renames the mod
folders for my ruby and sapphire mods so that they don't get mixed up
with anyone else's, like Zeg9's Weird Ores mod (https://github.com/Zeg9
/minetest-weirdores).
Also added some aliases for that mod so that their rubies are replaced
with mine. This seems to work in Worldgen but I haven't seen any rubies
that have already been mined be replaced, so keep an eye out for that.
