Thanks for looking into it!

It doesn't seem to be the same thing as 132739. 132739 is about not being able to launch to orbit. As you can see in the video, I can launch the fish to orbit - it just doesn't trigger the achievement.

But if you tested and it is fixed, then it is fixed.

Attached is a save, and a video of me not getting the achievement in that save.

It seems that it is no longer possible to get the achievement "So long and thanks for all the fish". I send a fish to orbit, but nothing happens.

I tested in Space Age. It worked fine in 2.0.73.

If you watch the video, another achievement does pop up just after. So in-game achievement popups are clearly enabled.

Here is a video where Frabj22 got the watch you step achievement, but the popup was missing. Frabj22 didn't have in before and had it afterwards, it just didn't display. You can see the steam notification popping up, but the ingame notification does not. Video: https://www.twitch.tv/videos ...

When force-upgrading an assembler 2 to assembler 3, the modules are sometimes not correctly applied. If the target assembler 3 of the force print has 4 modules, it sometimes happens that only 2 modules are inserted.

There seems to be a random element to this bug. In the attached video, I force ...

TLDR: Please make game.auto_save() work in replay mode.

As you know, it is not possible to "seek" in a replay, to jump to a specific point in time. If you want to see the game state of a replay at the 4 hour mark, you have to let the replay run for 4 ingame hours... Hence speedrunners will use a ...

I hope this is "fixed". It doesn't really make the game more fun, serve any gameplay purpose, if any low power situation breaks advanced circuit setups so horribly.

This bug has risen from the grave like a zombie, and is back in current 2.0.XX releases.

Thanks! Robot delivery seems to be much more efficient now.

So in the interest of not changing 100% speedruns in the future again: Is it on purpose that the pollution "absorption modifier" is still allowed to be raised to 400%? That odd one out setting still does doesn't invalidate achievements, but will make biters vastly easier to deal with.

In the attached save, I have ghosted 1000 iron to be delivered by construction bot to the silo. There are 1397 idle construction bots, while the iron is being delivered by 3 construction bots at a time, taking forever.

The inefficiency happens when there are machines with unfulfillable module ...

Demolishers can't destroy open gates.

Possible fix:

- only give bonus items once main item is complete.


Also possible fix: Count the ingredients as consumed for the current crafting cycle, whenever a bonus productivity item is created.

- doesn't give back item when cancel recipe like before (that could hurt player)

But please ...

Yeah, I have seen this too. There is no enemy or deconstruction request at the eternal red dot.

Dragging a smart belt on top of a ghosted belt fails to place the trailing underground.

@BlueTemplar From https://factorio.com/blog/post/fff-375 : "On top of that, the quality increase can be not only one level at a time, but you can get lucky and get more steps at a time, each additional step has 10 times lower chance of happening, so for our previous examples, out of the 1000 gears ...

Smart belt sometimes places an extra underground, when dragging a belt backwards onto an existing belt to extend it. This is a new-ish bug I think.
