It may be a feature but it looks like a bug to me: Eigenvalues[mat] does not return the list in the same order as Eigensystem[mat][[1]] This change in order means that the result of Eigenvalues[] cannot be used together with Eigenvectors[] i.e. mat.Transpose[Eigenvectors[mat]] != Transpose[Eigenvectors[mat]].DiagonalMatrix[Eigenvalues[mat]] Eigensystem[] is internally consistent.
