Issue description:

When trying to autocraft something that requires multiple Fluids only one of the fluids gets inserted unless the accepting machine is able to accept multiple Fluids at once.

What happens:

Autocrafting gets stuck when trying to craft with multiple fluids.

What you expected to happen:

First, one fluid gets inserted, then the other afterwards.

Steps to reproduce:

1. Make a pattern that uses multiple fluids. (Molten Dawnstone in my case it uses Molten Copper and Gold)
2. Setup the crafter looking at a tank.
3. Craft
   ...

Additional Comments

The Craft also is very slow due to the fact that it stalls for a bit whenever it cannot insert the fluid.

The only solution I found is using a tank that accepts multiple liquids. A tinker's smeltery was the only thing I could think of.

On version 1.6.4 where I initially encountered this, the complete system would get reset when it encountered this issue.

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

• Minecraft: 1.12.2
• Forge:2760
• Refined Storage: 1.6.6-300 ( from jenkins).

Does this issue occur on a server? [yes/no]
yes

But isn't that the fault of the mod? Most fluid tanks only support 1 fluid at a time. I can't do anything about that.

Kind of yeah, the embers alloy mixer needs the gold in one side and the copper on another. That means I already have to use a different tank as a buffer and then sort the fluid later.

The idea is that RS would insert one fluid and then waits until I empty the tank while it is unable to insert the other. Instead of what it currently does, where if a fluid cannot be inserted it will just be skipped.

This allows working around the issue outside of RS.

Refined Storage needs to be able to insert all the fluids (or even items) at once, to avoid mixing issues. So this will be a won'tfix!
