Nullification Genes are not compatible with one another

[Eagletanker]

I like to preface this by saying I haven’t gotten a gene in game so if this is already in my bad, but basically you can’t have SMES, Rad Resist, Anerobic and Thermal Resist on at the same time. You can chose one nullification gene at one time, and any after that would replace the one you already have. Makes it so you have to be more thoughtful in what you want for genes and so space can pose some sort of threat.
