not sure if you still work on mods for this game, but the lighthouses don't increase the number of sapphire that is earned from all sources which makes the game a lot more difficult to go through.

it dont apears the sphire

So I noticed that your mod is missing one change, the alternate crafting recipe for steel in the flower press. It's still the original steal and as such doesn't look right and if you look at the recipe for it and have steel created via your recipe it doesn't count how much steel you have. I was looking into trying to fix it myself but I haven't figured out everything that needs to be done to make certain modded things work, such as accessing a structure to either remove and item or to alter and existing recipe, I know that's what itemedit is for but not how to apply it to that specifc machine. Unless I missed something in the code for your mod that automagically converts steel from the flower press into steel changed by your mod.

I suggest to rename onyx to black diamond, it would fit better the idea of rare legendary gem. Copper and silver could be added as well.

Agree with Kivara's comments. anticipate to see new tools!
