I think steam achievements require network and are asynchronous, maybe some kind of "fire and forget" call would make factorio unvulnerable to this kind of issue, if that's possible...
I'm a software guy, but no C developer

Ok, thanks for the clarification.
Is this something, I or you should report to valve (steam)?

shouldn't Factorio be resilient/agnostic to failing or freezing Steam Achievement unlocks?
Also, why does an ascending cargo pod trigger an achievement? Is it for rocket launching related achievements?
I already unlocked all of those.

Today while open in the background, Factorio froze.
I got the usual Windows Dialog "Program is not responding" With "Wait for Program to respond" and "Close the Program" options.

THe music kept playing in the background, but trying to get focus back to Factorio was not working.

The only noteworthy ...

What I did when this occured:

I had a bunch of passive provider chests with reinforced conrete I wanted to relocate (around 90k),
so I placed 32 buffer chests, each requesting 4k.

I have around 3800 logistic bots in my network and after most of the material was moved, I noticed many
bots flying ...

When I move the camera all the way to the right or the left,
parts of the background sprites are cut off.
The rainbow/star background and the animated asteroid chunks are cut off.
The particles/dust are fine.

On my monitor this is only reproducible on the X-Axis, not on the Y-Axis, so I'm assuming ...

I had no biter eggs on me, and there were no aliens close by.

Trying to mirror a vertical ghost underground belt by pressing V plays a sound effect but does not change the direction of the belt.

Meanwhile, pressing R does, and if it's not a ghost, V works too, so it would have expected this to work for ghosts as well.
Probably affects other belts and ...

I've noticed this on Gleba, but other types of tiles might be affected too.

Steps to reproduce:
1. pick some tiles where you have placed Artificial jellynut soil.
2. put ghost tiles of regular landfill on top of them
3. before the landfill has been put down, you can now ...

I have a lot of stompers on Gleba which are completely frozen.

By the way, this control setting is found under "Advanced Interaction". it is the 16th entry.

Today I stumbled upon a control shortcut named
"Fast-Add wait condition" with the tooltip "Usable only in the space platform schedule GUI, for request satisfied wait conditions."
bound to Shift + Left-Click.

I cannot figure out what this is supposed to do. The description is not clear to me. I also ...

When Factoriopedia is already open in the space map view and I Alt+Click on one of the planet routes in the map UI (i.e. outside the Factoriopedia window), the Foctoriopedia page for Ammonia Ocean opens instead. (My player ist on Aquilo currently)
I would expect it to show the clicked planet route ...

I've created several parameterized blueprints for utility assemblers.
The product to produce is parameter 0 and I have a blueprint with an assembly machine and a electromagnetic assembler.

First of all: the product selection popup for parameter 0 ignores which machine it is a recipe for, so you get ...

Oh wow that is horrible
But it kinda makes sense I guess

Hi, I just hauled my first agricultural science packs back to Nauvis and they seem to be consumed way to fast.

I brought exactly 2.000 packs and immediately started research. Checking the production window I can confirm nothing has spoiled
and all 2.000 science packs has been transferred to the ...

During travelling to or from a space platform, the stars background sprite is rendered larger when zoomed in, whereas it doesn't on a space platform.

Shouldn't Steel plates produce iron plates in the recycler, since that is the only ingredient?
Currently, the recycler just destroys most of it's steel plate input and sometimes returns another steel plate.

TLDR input = output, seems wrong to me.

I increased the water features on Nauvis and almost got stuck on an island.
And this morning I saw a tanker on the river that looked like it was straight out of factorio

The Factory needs Boats! (Freighters)

A short fade effect may be enough, but the snow popping in and out of existance kills immersion for me
