In the paper On Elementary Embeddings From An Inner Model to the Universe, it is stated to that if $Ord$ is Ramsey (I.e. there is a proper class $I\subseteq Ord$ of good indiscernibles), then there is a definable class $M$ and some $j: M\prec V$. But, according to Generalizations of the Kunen Inconsistency, there can be no $j: M\prec V$ for $M$ a definable class?

Does this mean that measurable cardinals are inconsistent, or is something else going on?
