Let $L$ be an complete lattice. A lattice homomorphism $f: L\to L$ is said to be *join-incomplete* if there is an infinite set $S \subseteq L$ such that $f(\bigvee_L S) \neq \bigvee_L f(S).$ If $f:L\to L$ is join-incomplete, does there exist a lattice homomorphism $f:L\to L$ such that - there is $S\subseteq L$ with $f(S) \subseteq S$, and - $f(\bigvee_L S) > \bigvee_L f(S)$ ?
