Nullification Genes are not compatible with one another

[Ikea]

While technically thermal resistance being there isnt rng, theres various factors that go into it, all of these factors are unreasonable for a person to account for (should we expect antags to check manifest for who is geneticist that round every time if they plan on using a weapon?) Like, idk I guess you could just bomb genetics every round but eh? That doesnt seem good either.
