Issue description:

In the Purification Chamber we can create Flint using gravel and flint. It does not make sense. Why waste a lot of flint to create ... flint?
For this I completely lack the recipe as from the gravel itself to create a flint.

Steps to reproduce:

1. Remove in the recipe required as a flint raw material to create from the gravel as the final flint product.

Version (make sure you are on the latest version before reporting):

Forge:
**Mekanism:1.12.1-9.4.1.326
Other relevant version:

The problem of the device was a problem with the pipes.

The purification chamber needs oxygen for everything, and that's available from gas tanks or from flint. It also happens to be able to create flint. I don't see an actual bug here.

the only flint recipe i can see in the code is gravel + oxygen -> flint, so I'm not sure where you're getting a flint from flint recipe.

Please show a screenshot illustrating.

I believe the purple slot is for the gas input, so that looks like a bug with the JEI integration only. No idea where the 10 items thing is coming from.

A better option would be to add a recipe to the crusher eg 2 blocks of gravel for 1 flint.

Why though?

When Gravel and Flint are dropped, the unit consumes 10 flints before producing 1 flint. Check out these ingredients from the photo.So, rather, this is not just a JEI problem, because the device actually uses these components.

Then show me the machine doing this; your image only shows JEI

If the cause was in JEI then Gravel + 10 Flint = 1 Flint would work and one unit would actually work after inserting these components. So, in the scripts, it allows for the selection of components.

Why though?
Because I did not find the recipe for obtaining Flint from the gravel outside the hand picking a gravel block.

Please, here I give 3 screenshots from the next stages of production.
Ops, to produce 3 flints need about 40 flints!

Can the error occur only in the game version on the server?

Problem 2
Should I start a new application? Because I have already set up 2 times, but after laying the pipes all over again for a short time back to normal.

I also have serious problems creating a chain of production boxes - Smelting Factory - Formulaic Assemblicator. I repeatedly checked all connections. And if something works properly it would seem that everything is fine. Unfortunately, when I move away from this chain of machines and after some time I return to the factory, it turns out that once again the Chest to Smelting Factory does not work and the tubes do not take the raw material. The only way to fix it is to destroy the pipes and reposition them, even without changing the configuration of the equipment. Only if you move away from the device again will cause you to stop working and not resume it.
Breaking the transport chain does not always happen between the boxes and the Smelting Factory. Sometimes between Smelting Factory and Formulaic Assemblicator. But always after a while the chain of transport is always broken.
I do not know if I should report this problem separately, because it is quite complicated and very frustrating, because I fight with him for a few days.

I add that the described production chain I run in the game as a client on the server.

I've looked into this further, and there is no issue regarding flint in the Purification Chamber - Flint is a source of oxygen.

The pipes issue is a known issue. See #4676

If Flint is the source of oxygen, it makes no sense to create Flint on this device. I would suggest moving Flint from Gravel to Crusher.

Flint is a source of oxygen, not the source. Most people get their oxygen by separating water. And a change like that would break a lot of existing setups for no real gain. Also, gravel already becomes sand in the crusher.

Sand is quite easy to get raw. Flint does not. I still think it would be logical to use a sandstone crusher to get sand. Although, as I wrote, it is easier to sand directly from the biomes than the flint. All the more so since there is no way to obtain flint than to split the gravel manually, which is a very laborious task.

But I will not insist.

The purifier is the way to get flint. Just feed it oxygen from separating water.

Please, here is a screenshot showing the recipe. I do not remember how many flint it takes to create flint, but I guess I have to use 10 items to get 1 piece of flint, which is nonsense.

Flint is a form of quartz, which contains oxygen. It makes sense to be able to make it and to use it as a source in the same machine. The end.
