I feel like this would require almost as much infrastructure as a proper defense...


No it's just... halfway between "clear your entire pollution cloud" and... not doing that. You go out and clear nests and worms from your pollution cloud, but you always leave one alive. Now a larger portion of ...

2.1 added a minimum distance before a chunk is considered valid for enemy expansion, and it only takes one nest to invalidate all chunks in a 5x5 area.

So players can leave one nest alive in every enemy base to reduce the amount of pollution absorbed - and thus the frequency of attacks - yet ...

EnemyEvolutionMapSettings are used in MapSettings, but EnemyEvolutionMapSettings does not list MapSettings under "Concept used in".

(MapGenSettings is similar to EnemyEvolutionMapSettings, and has better documentation of where it's used.)

2.1 seems like the last opportunity to elevate Automatic Underground Pipe Connectors from mod to vanilla.

The author of this mod hit a roadblock and never did find a good way to automatically place concrete or foundations on Aquilo and Vulcanus.

I've tried every syntax I can think of. Brackets, angle brackets, curly braces, spacing, no spacing, commas, quotes... and none of them produce an OR search on the respective keywords

TL;DR
Clicking a slider, signal, or text element should enable it, when possible.

Clicking one of the filter slots should enable "Use filters" and open the "Select a filter" GUI.
Clicking the whitelist/blacklist toggle should enable "Use filters ...

Thanks for the report however none of the mentioned things are bugs.

With recipes that have fluids, that’s up to you the player to handle however you see fit.


The thing is, if we try to make an auto mall, fruit and barreling have to be translated into their respective recipes. Which is fine ...

they are recipe signals, not entity signals.


Looks like barrelling and unbarreling are sorted before logistics and production groups as well. Curiously, barrelling and unbarreling change the position of the assembler's pipe connection, which seems rather inconvenient for an auto assembler. It ...

The water_connection_patch isn't being updated when land tiles are placed over water. They are also not being updated when land tiles are removed from water.

When using "set recipe", Assembling Machine 2 and 3 do not respect the normal sort order for:

Yumako processing
Jellynut processing
Nutrients from spoilage
Wood processing
Nutrients from fish
Nutrients from biter egg


Normally a wood chest is sorted before ...

It's the most feature-rich blueprint website, and its developer is actively fixing issues.

2.0 is almost a year old and factorio.school still doesn't have a working blueprint renderer. If you do a deep search, half the thumbnails are missing.

Background

I had an idea: To reduce the number of mines in a minefield by placing smaller, isolated clusters of mines and using walls/pipes to direct enemies into them.

Something like this, or so I hoped:

But while testing designs, I kept having inconsistent attacks on the ...

You mean the best one.

TL;DR:
Make uppercase hexadecimal numbers work in logistic groups, combinators, control behaviors, etc.

What?
Typing 0xffff works but typing 0xFFFF does not, and I think it should.

Why?
I tried various prefixes and postfixes to see if hex was supported at all, and none of them worked ...

Logistic groups are currently a subsection of the logistic network page. But logistic groups are actually a pretty big system used in many places:

Surface requests: logistic chests, rocket silo, player character, car, tank, spidertron
Orbital requests: space platform hub, cargo landing pad ...

BrainGamer_ wrote: Thu Oct 02, 2025 4:58 am The important thing to note is that hex numbers must be in lowercase, so 0xff instead of 0xFF.

Would support for uppercase hexadecimal be a bug report, or a feature request?

TL;DR
hex.png

What?
Please add hexadecimal support to number fields. Particularly in logistic groups, combinators, and machine controls.

One option would be a "0x" prefix, eg: 0x7FFFFFFF
Another option would be an "h" postfix, eg: 7FFFFFFFh
The second option is one less keystroke, but ...

1. Deconstruct any underground belt exit
2. Wait for bots to remove it
3. Undo it
4. The underground belt exit will be replaced with an underground belt entrance. Has the wrong rotation too

Much better!

This is still present in 2.0.66
Undo-redo does not rotate underground belts that were rotated by smart-belt dragging
