Gameplay Yorick Ghoul bug

Anytime you play Yorick top (yes, people still play Yorick) lane and summon a Ghoul (more specifically Omen of Famine) instead of the ghoul spawning on the targeted enemy champion, it spawns next to a terrain wall. For instance, you can be fighting someone in the middle of top lane and cast Omen of Famine on the champ and it spawns in the top middle bush. This gets frustrating as Omen of Famine is his sustain. This is the spell that encounters the most frequent "teleport" of the ghoul. The ghoul is also summoned to a random location when it occurs, its not even a fixed point on a terrain wall. Sometimes it is near river, sometimes in a bush, others closer to the enemy tower. By the time the ghoul gets to the champion its timed life has basically expired.
