Those are trash slots, not internal storage, they have to be cleared for it to start a new cycle.

You did not attach the save, but based on the log it is corrupted because of a bit flip so likely a hardware issue, see 114778. If you post the save a dev might find the time to fix it, but unless you replace the hardware something else will break eventually.

Looks like system instability, see 114778. Make sure you are on the latest bios for the raptor lake defect.

Is it because it already calculated the path and doesn't want to change it?

Yes. Path calculations are expensive, so recalculations are only done in certain situations. Alternatively to extending the stacker you can make the bays in your stacker stations themselves and add their name in the ...

That is a feature request and you already made it.

I don't see a difference, they are equally offset in both vertical and horizontal rotation because of the 2x2 rail grid.

Vanilla or not, we need a save file.

pN_im is the item count of the m-th ingredient of the N-th parameter, fluids are not items and do not have an item count.

But PENTAPOG eggs can't be a part of BUG eggs and wise versa, it is even different planets!

Nutrients are part of the penatpod egg recipe. Nutrients are not raw materials. Biter eggs are raw materials. You can make nutrients from biter eggs. -> Biter eggs are raw materials of the pentapod egg ...

It seems the system as a whole is struggling in that instance, it is not one thing that suddenly takes longer, everything does. I'd start by checking temperatures and updating drivers.

Pollution per production cycle does not actually change when switching from stone to steel furnace.

No, the crashes have nothing to do with each other and are independent of user input. Have you checked your bios version?

Your system is unstable, see 114778.

That is not a bug:

When used in both the input and output of a decider combinator, anything will return the first matching signal following the order of precedence as they appear in Factoriopedia

If you want signals to be passed individually you can use EACH.

The crash has nothing to do with surfaces being deleted. It is crashing in GUI rendering code which is likely not a software but a hardware problem, post more logs with crashes and provide exact steps to make it crash if you are able to.

And make sure you are on the latest bios version for the ...

As before, keep it brief and stick to one idea.

Those saves seem to have multiple corruptions so this is a hardware issue, see 114778.

Edit: You really need to replace your hardware: 131961 132705

As before, keep it brief and follow 47316.

I close this, as before keep it brief and follow 47316.
