One suggestion that could solve all the weirdness with prevented actions etc. that I haven't seen mentioned in this form is the following:

The basic idea is that there could be special pipes for each type of fluid which are placed by the player. This way, there would be no issues with any of the ...

For the pipes I think several people have offered better suggestions than just preventing mixing. The entire problem with pipes is that they are this special thing that users can't interact with, and they have all of these partial item and weird properties going on. If we could start over on pipes ...

Why is this something you can't fix? Why is that happening at all?

Lets describe what I see going on:

1) The crude oil pipe is empty but locked by the assembler.
2) Placing a ghost disconnects part of the pipe making it ...

One suggestion: Make a "disconnected underground pipe" graphic. Like a capped pipe going toward the ground or something. Used for any case where you've placed one end but not the other. Would be useful for detecting these pipe network changed because a pipe in the middle was destroyed cases. May ...

I don't care much about having fluid mixing prevention. But i would like to be able to design flexible systems, which change recipes dynamically and use different fluids delivered using a pipe network wich is connected to multiple different fluid sources by pumps of wich only one is enabled at a ...

Just wanna throw my vote in for reconsidering the ban on fluid mixing.

I think the current mechanic is more annoying than the occasional accidental mixing. And honestly, a lot of that is just because "well that was stupid" is far less frustrating to me than "WHY won't it let me build this here ...

that is the whole point

About fluid mixing. Inputs on assembler and chem plants have never mixed fluids so they should not set fluid filter or hinder building pipes around them.

For the new fluid algoritm I must say I am not a big fan. Real pipes is usually filled with fluids and is not half empty as in factorio. The ...

Please stop messing with established mechanics. Was fluid mixing annoying? Yes. Is this better? Not necessarily, your gif shows a quite awful example. Does this change add to the game? Absolutely not.

Feels like so much cool stuff could have been done with all that time.

I feel like my favorite ...

What if the underground part of a underground pipes really existed, just didn't connect sideways? It would not be possible for undergrounds to cross each other, one would have to go over the surface. On the other hand, no weird reconnect behavior.


I have a proposal for underground pipes ...

Yes, I have this on my list.

Hi, this is quite certainly a duplicate of 75552. It should work in the next version. Sorry for the trouble.

Does sound like a duplicate. Please, let me know if it still does not work in the next version.

I have changed the mixing fix to remove the new entity so this does not happen anymore.

This is very similar to the mixing by replacing the ghost by a pipe, just a little bit different as it does not connect to fluid systems. Since I can't easily prevent this one either for the same reasons, I have added this to the fluid mixing fix - basically the boiler would just disappear after you ...

Another bug I introduced when fixing those various length pipes.

Actually exists in vanilla

It is not connected.

I have made a mistake when fixing something about underground pipes with different lengths. Your save will load in the next version.

Fixed for the next release.
