  We observe that there exists an associative finite dimensional
$\mathbb{C}$-algebra $A$ of finite global dimension, such that the bounded
derived category $D^b(A)$ of finite dimensional $A$-modules admits an
admissible subcategory $\mathcal{P}$ with vanishing Grothendieck group
$K_0(\mathcal{P})$. In other words, $\mathcal{P} \subseteq D^b(A)$ is a
phantom. Using tilting theory, this follows directly from a very recent example
of a phantom for a smooth rational surface due to Krah. By work of Aihara &
Iyama, this also leads to new examples of presilting objects that cannot be
completed to silting objects.
