Make all critters immune to the effects of miasma

[StaringGasMask]

Please, make this a reality. The fact that a changeling can lose one of their limb critters to miasma without having any counterplay other than going through somewhere else is too crippling for the cost of the critters.
Not to mention the little sense that these critters surviving in space just fine but dying to some miasma makes. If they don't breathe, they don't breathe
