Mutagen problem

When I try to craft the mutagen from the standpipe book it does not acknowledge one of the ingredients. I am using version 0.B-2570.

I’m a bit tied up fixing some JSON at the moment, sorry–what ingredient? Little more detail please.

Make sure you arn’t confusing Serum and Mutagen. They are different.

I was making elf-a mutagen and it would not recognize the bird mutagen in my inventory.

Just tried and the stuff worked fine. Thinking it’s fixed in latest.
