TLDR: In base game factorio, when hovering the formula entry for a blueprint parameter, it tells me that "pN_r" is the crafting time of the parameter but it is actually something else.

Steps to reproduce

Enter a map in base Factorio (no mods, no dlc)
Import the blueprint string and start ...

Environment

Steam edition of Factorio on Windows. Steam input is disabled.
I used Nintendo Switch Pro controller

Steps to reproduce

Pair the controller and make sure Factorio recognizes it
Open the controls menu and switch to "controller" controls
Change the icons setting to a ...

Steps to reproduce

Disable all mods and dlc
Open any map
Open tips and tricks
Under "Copy-paste entity settings" view the "Copy-paste filters" tip


Expected
Splitters display a filter for circuit network

Actual
Splitters display a filter for :any-quality: circuit network

Here is a save file.

My reproduction steps:

• Open save in base game factorio (space age, quality and elevated rail mods should be off)
• Open game blueprints
• Right click any of the blueprints to open preview
• Press Esc

The prompt to save modifications should show up.

TLDR: Attempting to close a blueprint preview with modded content, without having the mod enabled results in a "save modifications" prompt.

Steps to reproduce

Put a blueprint in the blueprint library that contains space age content
Turn off space age mods
Enter a map and open the blueprint ...

You can chain multiple of these together to get arbitrarily random numbers from 0-99; 0-9,999; 0-999,999; or you can remove signals to get a smaller range. Or you can add "Quality" variants of each signal to expand the range even further while maintaining an even Numerical distribution.

What?
Inside blueprint parameter formulas: Give access to variables that correspond to the absolute coordinates of the placement location, and when dragging, the coordinates relative to the first location. (Or the coordinates of the first location which can be used to compute relative coordinates ...

I still think it would be beneficial to have achievements that specifically target the practice of "cranking up the numbers" in the world generator, by making playing with a specific preset the challenge. It would be interesting because players wouldn't be able to skip having to expand by making ...

If an item or fluid has multiple recipes, the additional recipes already get extra signals. So for selecting the correct recipe, the item's or fluid's signal itself can correspond to the default recipe, which is the recipe the item or fluid is merged with on Factoriopedia. The additional recipe ...

What?
The game should not auto-delete or auto-merge entries in the parameterization that have the Parameter checkbox checked, even if they are unused.
Essentially, please fix this bug.

Why?
Deleting or merging parameters is an inconsistency. If the player checks the parameter checkbox, it ...

TLDR: Elevated rails sometimes do not get built when undoing/redoing in editor with instant blueprint building (and deconstruction) enabled.

Steps to reproduce

In editor, enable instant blueprint building and deconstruction.
Place the following blueprint.

I second this. It would be really great if selector combinator had a [0,N) random option with N being an input signal or a constant. It could also support the Each wildcard giving one roll per input signal.

I do not think the behavior that the train always stays at the stop with the same name is any useful. I also tried to get it to leave by giving higher priority to the other stops, but that did not work either.

Expected behavior is as following:
When a train wants to depart for a stop with a given ...

What?
Assembing Machine's "Set recipe" should set recipe based on the highest valued positive valid signal .

Why?
Currently recipes are set based on "first valid signal" which can be counterintuitive sometimes. There is also little practical benefit to this system.

This assembling machine ...

List of in-game tracks that I think deserve a bit more love in the soundtrack:


Fulgora 1 (Don't tell me 3:30 is completely missing!!) :cry:
Fulgora 3 (Notable section: 5:18 - 7:00)
Vulcanus 7 (Really starts going at 3:00)
Gleba 6 (Notable section: 4:26 - 7:15)

TLDR: When hovering a quality machine or module in the upgrade planner, the tooltip only shows the base machine stats and no quality effects.

Steps to reproduce:

Add a rare assembling machine 3 to a slot in an upgrade planner.
Observe the tooltip of what was just added.


Expected:
Tooltip is ...

What?
Make it so that space platform maximum item requests only drop the surplus items onto the planet specified in the "import from" box. In other words, the entirety of the filter, both the minimum and maximum should only be active while the platform is over that planet.
Why?

In this case you can fix the bug by rounding each randomly generated period to the nearest value with no more than 16 fractional bits.

If P is the number of times the asteroid does a 360° turn per tick then P*65536 (P << 16) should be an integer to prevent snapping. Which is the case if P has no ...
