It's not completely clear why, but emptying my mods folder solved the problem. I spent some time before this problem appeared downloading a large number of random mods for the sake of doing automated testing, and at least one of those mods makes it impossible to browse multiplayer servers.

This crash occurs when attempting to browse public multiplayer games in the server browser. After receiving a response from the server, the game will crash with an unexpected error. This crash does not occur if I disconnect my computer from the internet and do the same thing. Instead, the game will ...

Following instructions for the regenerate_entity function https://lua-api.factorio.com/latest/classes/LuaSurface.html#regenerate_entity , while it is able to generate resources that already existed, it can not be used to write a migration script that adds a new resource to an existing world.

To ...

To reproduce:

1. Disable all mods.
2. Go to "Mods/Explore."
3. Type "MT-lib" into search bar.
4. Download "Midnighttigger's Library."
5. The game will throw an unexpected error.

When one attempts to research a technology with the "send-item-to-orbit" research trigger, sending the specified item into orbit will not research the technology, as the game's tooltip indicates.

This problem appears in the mod "Muluna, Moon of Nauvis," where the ...

In Paradox games like Europa Universalis IV, the game has all in-engine variables stored in a file called defines.lua. In this file are all variables that are central to how the game operates, including variables that determine the aggressiveness of AI, the way that being ahead of time in technology ...

Certain mods such as Entrenched Enemies add high-quality variants of existing enemies with more HP and a longer spitting range. In cases when mods like this are installed, it would be helpful to be able to add a flag to a mod that enables an interface to select target priority of turrets based on ...

This is a bug within Factorio's documentation, not with Factorio itself.

The current version of Factorio's documentation does not document the "auto_recycle" recipe-prototype feature, which appears to control if a recipe is reversible via recyclers. Without documentation for this feature, modders ...

At the moment, it's not possible to parametrise entities that filter only by quality. Adding the ability to parametrise quality filters would save a lot of time when making quality filters.

I've made some changes to the "Application directory" wiki page to say that blueprints are now backed up by Steam Cloud, while adding instructions on how to transfer blueprint collections between installs. Hopefully that will stop other people from struggling with this issue, as I have.

I was not aware that blueprints were backed up in a folder within Steam when Cloud Save is enabled. It doesn't look like that's documented on the Factorio Wiki, at least not when it comes to blueprint backups. Every post I could find on the topic said that Cloud Save does not save blueprints, but ...

I usually play the DRM-free version of Factorio, but last night, I installed the game on Steam so I could play with some friends via Steam. To make this fresh install identical to my other install, I decided to copy config.ini and all three blueprint-storage files (blueprint-storage.dat, blueprint ...

To better understand the new "Set Recipe" circuit connection, I decided to try making a military science setup controlled solely by SR latches that write recipes to assemblers in a sandbox world(filename "mil sci test"). While building this, I found that of the five signals that can be written to ...

Occasionally, Factorio will crash on startup, but never twice in a row. Every time that Factorio has crashed for me, it will open correctly on the following attempt. I do not know how to replicate this bug.

I have posted all necessary files in this thread. I don't know why there are two copies of this thread.

I am attempting to convert a long-running freeplay save into a scenario. The plan is to move all player-owned buildings in the save to the enemy force. When playing the scenario, players will need to steal items from undefended portions of the hostile factory in order to destroy the defended ...

After loading my game in 1.1.0, the game worked until it attempted to autosave, which caused the game to crash. Saving the world manually does not result in a crash. The world used and the log file are attached.

If you are only modifying vanilla recipes you can use data.lua with a dependency on base.


This code does exactly what I was trying to do ...
