I mean that zirconia (the white cubes) recycles into pentapod eggs
I was surprised to find pentapod eggs appearing on my sushi belt on Fulgora. Zirconia does not recycle into itself but into pentapods because the recycler undoes the zirconia-from-egg recipe. The recipe needs auto_recycle = false to keep this from happening. I think it may have only started happening with the 2.1 update.
