Hi there.
Biter eggs looks like the only spoilable item that does not spoil until removed from spawner.
I tried looking into docs & runtime prototype data, but didn't find any property that relates to such behaviour. Can you help me identify the source of it?

Good guys on Discord suggested this: https://lua-api.factorio.com/latest/pro ... ine_output
This has no "spoil" nor "fresh" in neither name or description. In fact, this has no description at all.
