[2.0.72] Freeze for unknown reason

[miege1000]

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 thing I did when this happend was switching network connections, as my wired connection was slow and
unreliable, so I turned on Wifi and switched networks.

I have created a dumpfile before ending the process, I hope this helps:

Let me know if you need more information about my hardware or operating system...

Looking at the stack, it looks like the freeze is inside of a SteamContext. Because of that i do not see anything here that needs to be fixed on factorio side.

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.

Failing as in the function call returns an unknown/invalid value - it is. Failing as in the function call never returns - there's nothing we can do about that.

The expectation and contract is: calling the function with valid arguments returns some value and we process that. In this case, that failed to happen and there's nothing the code can do since it's no longer running - but stuck inside some steam logic.

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

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...
