Please do not post ideas under bug reports.

You are seeing effects caused by the 100 million health of the entity while the game is not focusing too much on health and stores health values as 4 byte float representing a health ratio (1 = full health, 0 = empty health). In order to deal 1 point of damage, the health ratio would have to go down ...

1. Is this statement inaccurate? - "collision check is something that is already happening anyway . We're just getting a (almost) free piggyback ride on it"? If it's indeed inaccurate, how far is it from being such?


If i am reading this correctly, you are assuming that all entities do collision ...

Disclaimer
I could be wrong in some of my assumptions here, but this is based on what I've gathered from forums and API docs. Please correct me where I'm wrong, though :)

TLDR
Collision cheap.


Indeed you are wrong. Collisions are not cheap. There are 2 parts to collision checks: first is ...

This is a feature request, moving out of bug reports

If you go to "Other settings", do you have "Automatically enable new mods" turned on? (it is on by default).

Thanks for the report. I will classify this as Not a bug because the most likely cause of what is happening is that your assembling machine is also set to "read ingredients" and those values when sent to a circuit network are making assembler to select a different recipe. https://forums.factorio.com ...

Unfortunately i have to classify this as Not a bug. Values on a circuit network are limited to a range [-2 147 483 648, 2 147 483 647] (also known as int32) and i am not seeing it ever changing at this point of game development since there are players that expect it to be behave this way or it would ...

Thanks for the report. Issue is now fixed for 2.1.12.

Thanks for the report. This is Not a bug.

As part of 2.1 changes, science packs no longer store durability on item which means item is consumed as soon as lab starts consuming it. If the item was present in the slot as you are asking it would be a problem because you could take the item out of lab ...

Thanks for the report. Issue is now fixed for 2.1.12.

Highlight for allowed modules is too much of a scope creep as it would require finding all places where lists of items show up like modules, furnace, burner fuel etc and i am not interested in handling all of them. Not doing that.

As for flasing, i used solid highlight for recipe ingredient, not a ...

Thanks for the report. This is Not a bug.

Rationale for drop selecting other side of belt when entity is mirrored is to make flipped blueprints remain functional. Given that recycler when flipped would start dropping onto other lane but on a different tile is acceptable because when blueprint was ...

Thanks for the report. Issue is now fixed for 2.1.11.

This was never working as you are suggesting it should and it would be a significant behavior change which would need more thorough decision making than a simple bug report, as such i am going to mark this as Not a bug because you are posting a feature request.

Your code is still bugged, you are setting alert_message on a copy.
is bugged. In a correct code there will be somewhere

Thanks for the report however without reproduction there is nothing that can be done about this report. I have reasons to suspect that this is not factorio's fault but it is your hardware that is failing given that i was able to find at least 3 automatically uploaded crash logs from what appears to ...

Quick look at the desync report suggests it is related to fluids which makes me believe it may be the same issue as https://forums.factorio.com/134751 and https://forums.factorio.com/134903. There is some issue related to assemblers that craft fluid recipe and changing machine modules (or ...
