Id effect Nasty_Poison

So I was just having some fun making characters and trying new builds. And when my character shot himself with some Spider Serum and got Strongly Venomous, That’s some good shit I thought. But every time I attack with a Mutation based attack I get a “Invalid Effect, ID: Nasty_Poison”. I tried to fix it myself by going into the effects menu and sadly came up short. The bug is in the 79a3689 Build of the experimental. I hope you guys fix it. I love that mutation.
