Are you playing with any Mods, perhaps one which removes Biter Eggs? (but does not change this Technology) It should still be Visible in the Tech tree on Vanilla... Or have you just not "Triggered" the Biter Egg ...

Re: Non-blocking saves?
As far as I understand, Windows has a copy on write for memory as well, however you need to explicitly design and code, while with unix-like systems all complexity is completely hidden inside the fork() call. All you need to do is fork() without complex initialization, and you just need to check ...

This is the API page I was looking for; thanks! Factorio would need to add SteamWorks support in order to implement this properly… that seems like a lot of change.atomizer wrote: Sun Jun 15, 2025 10:08 pm connect command works only with servers that use the Steam Game Server API, which would need to be implemented in the server.

Yup, the Turret has run out of Ammo. The Inserter will not try to grab a Different ammo type until the Turret is in “Out of Ammo” state (and the Alert is triggered); it then takes a few Ticks to Grab & Swing the Inserter arm to the Turret. Once the new Ammo is in the Turret the alert stops ...

Re: Steam protocol server connection
Factorio itself does not speak "steam://", but it is already possible to "launch the game and make it immediately connect to the server". There are existing Command Line Parameters --mp-connect and --password to have the client automatically connect when launched.
