Cloning should not clone mutations that prevent cloning from finishing

[Mouse]

*gasp*

Oh no, a unique situation that requires some supervision of the cloning vat.

Oh no, medical doctors have to actually use some deduction, something that MD mains actually crave, oh nooo.

Sarcasm aside - I think this should be a feature.

There is no way to tell if someone has Blood Toxification short of stuffing them in the gene scanner (which doctors don't have access to), hoping that Blood Toxification has been researched (it's not very common to find in DNA), and hoping that whatever gave the stiff Blood Toxification didn't give them so many genes that it's impossible to see all the ones they have.  It's a functionally undetectable method of bricking cloning for however long it takes for a bunch of very busy people who aren't timing things to notice that that particular cloning hasn't finished.  Unless they're constantly monitoring the cloner they're going to assume that a particularly long cloning session is going to be a new one.

For what it's worth, the doctor mains I talked to didn't like the idea of cloning mutations, full stop.
