Reproduction:

Was making teslium using wirechem. Managed to make gunpowder alongside multiver and sulfur in a chemical mixer. When using that mixer connected to a chemical filter I was able to filter out both sulfur and multiver, but gunpowder isn't able to be filtered. Even tried filtering every chemical beside gunpowder and using the "unfiltered chem" circle, but that didn't work either. Gunpowder simply isn't able to be filtered :(
