Is there a way to prevent(or resolve) item spoilage picked up by inserter?

[ik1ne]

I thought I've built a completely lock free Gleba factory, but I can't figure out how to prevent this one scenario(happened only once).

1. Inserter picks up a spoilable item, which is just about to spoil.
2. While the inserter arm is mid-air, the item spoils, making it as an invalid input.
3. The inserter can't put item inside the assembler(or biolab), because it's now just a spoilage.

I think this can only be prevented by game rule change where items picked up by inserters doesn't spoil. Any ideas?

If there is a machine that does not allow rhe placement of spoilage into a trash slot where another inserter can remove it, that might be a bug.

I don't know if this will work, but it's possible putting another inserter pulling items from the first inserter will pick up the first inserter's hand stack.

Just to confirm that spoilage insertion is possible, I built a test scenario (in version 2.0.23) that makes this happen 100% of the time:

The left yellow inserter is picking up yumako mash that spoils in hand, and it is successfully inserted into the biochamber as trash, then removed by the inserter on the right (which also removes items that spoil inside the biochamber).

I'm having this issue with the captive biter nests. The bioflux spoils while in hand and locks it up as the nest doesn't accept the spoilage at all. I tried using another inserter to grab from the original, but that idea was a bust. I don't think this can be prevented and is fairly annoying to lose your biter nest.

The only solution I can think of is to wire the inserter to an alarm and have it go off if there is spoilage in the hand so you at least get a warning. I'm wishing there was an automated way out of this problem.

I've also been looking for a solution for this.

I think the problem stems from when bioflux spoils mid-swing. The result is something I haven't been able to automatically resolve.

Best I could come up with:

Use a requestor chest with request for more than one stack of bioflux, then on the inserter prioritize fresh.

While I might not call it a bug, it does seem 'buildings' have a trash slot for spoilage to prevent this from happening. It seems the captive biter nest however does not? It's really hard to say what is happening in my situation as it's always when I'm off planet for hours.

EDIT: So I recaptured my nest with the spoilage still in hand... it DOES have a trashslot (when captured) so make sure you have that inserter pulling spoilage out too.

I found a better solution:

When a starved spawner is re-converted the spoilage in the bioflux inserters hand magically disappears. So having a rocket turret nearby with capture bot rockets is a fail proof method. Not sure about the captive biter spawner having a trash slot like you claim, since it only works at the moment of re-capture
