Unstable Spider blood

I am unable to drink the blood of the Unstable Spiders found in the cursed forest even though they have visible creature blood type. I think I was able to do so in the past, but now the press f to drink blood icon isn't even showing up. So I think it's bugged. Also I am unsure if this is another bug or if it was a deliberate change but the spiderlings have no blood type and I remember them having blood I could be mistaken though. Anyway the unstable spiders having blood but being undrinkable is more obvious to me, unless I am somehow doing something wrong.
