Diagonal rails are shorter than rectilinear ones, resulting in diagonal rail lines costing more per kilometer. This goes against the intuition that rails are the same regardless of their orientation. The horizontal/vertical rails need to be about 30% shorter, or diagonals need to be about 40% longer...

Similar to Key modifiers in on_gui_click, I would like to have modifier keys in on_lua_shortcut so that a shortcut button can act differently based on modifiers.

Ah, reassuring to see that other people want the same improvement.

TL;DR The state of the trains dialog box should persist when the dialog is closed and reopened. What ? When the trains dialog box is used, closed, and reopened, the view should remain the same. Specifically, the search string, selected tab, and selected list item should remain the same. In the atta...

Pretty sure during the Quality discussion, most people came to the conclusion that items with different Qualities don't stack. That Quality FFF (https://factorio.com/blog/post/fff-375) show its possible to use splitters with only quality as a filter condition. If different Qualities items don't mix...

Since the Factorio blog has presented new filtering features, I'm requesting prototype flags so mods can put the features in advanced inserters and belts only. This would be similar to how vanilla factorio only allows filtering in a more advanced type of inserter. * Enable item filtering in splitter...

How does quality interact with stacking and filtering? Can a belt splitter split stacks by quality? Are inserters dexterous enough to pick one high-quality item from the bottom of a stack like that trick where you remove a tablecloth without disturbing the plates?

TL;DR Allow mods to define how module effects scale (instead of simply adding up all effects). What ? Provide the following modding interface for defining effect scaling curves and associating them to recipes. An effect scaling curve is a one-input, one-output, side-effect-free function defined by ...

Is there documentation for the resource config data structure? I couldn't find it in the mod files, the mod page, or this forum. I want to adapt my mod to work with RSO. Copying settings from one of the basic ores won't do what I want: the mod uses a custom noise function so that the resource's avai...

I disabled stream-from-disk, and this does prevent the hang.

Appreciate the quick work to fix it. This means I should re-enable stream-from-disk after the next update, right?

Setting music-volume to 0 does not prevent the problem from happening.

I tried --disable-audio and it didn't hang in an hour. That seems to avoid the issue.

How can I check the stream-from-disk setting?

Factorio randomly hangs after I updated to the latest core using the prompt that the game shows on startup, before the main menu. It didn't hang before the update. I don't have a way to reproduce the hang. I estimate it runs 15 minutes on average before hanging. It sometimes hangs on startup. The at...
