I set-up my rocket production and went on to start producing satellites. I ticked the "Auto-launch without a satellite." checkbox so the rocket would launch the moment a satellite makes its way in.

Before I even started producing satellites, I got the orange pause-popup saying I launched a rocket without a satellite. I was at the other end of the factory, there is 0% chance of my launching it by accident, and when I ran to the silo it just started building a new rocket, the checkbox still ticked.

Obviously, the silo should've waited with a rocket up and ready, until a satellite was inserted in. Instead it just launched and wasted the materials.



As I tried to reproduce the bug on the next "cycle", I found out that the rocket launches because an inserter puts processing units into the rocket inventory. The rocket launches because it's inventory has something in it - but it's not the satellite, so you get no reward.

No mods are involved.

All in all, the bug is that inserters will insert processing units into rocket inventory. The auto-launching feature doesn't recognize for the content of the inventory since it's only meant to accept satellites, and launches without a satellite.



I have attached the save file. If left alone, the rocket will momentarily auto-launch without a satellite.

The rocket generally accepts any item in the cargo and it is intended. It is useful for mods and possible gameplay additions.
The wording might not be precise, as it might be something like "auto launch when cargo is full".

Ah, sorry, it's the wording that threw me off. It's working as intended then, but the wording is a tad misleading.

I changed the word satellite by cargo.
