Mutant plants not splicing properly

I'm pretty sure that's what they're coded to do.

Just for the sake of clarity, "coded to do" does not always equal "intended to do". Most people view bugs as things that are broken, but "doesn't do as desired" is just as relevant a bug.

Whether that's what applies in this case I can't be bothered to look up, partly because commenting is terribad and so understanding intention is pretty tough.
