I’m confused, I was asking if you let the hexagons visible and unlink interactions.
Also are they IX1 or IX2?
What happens if you let the interactions only on odd rows? (so no hex with IX overlap ?)
If ovrlaping + interactions re the issue, you should be able to find an elegant solution. As your grid is now, you have a dirty hover on the bottom of hex: when hovering the bottom of an hex, the trigger is placed on one of the two hex below, that’s just html logic, bounding box, box model thing. Maybe your interaction would be better placed on a dummy trigger, like an element in the middle of each hex, hence those triggers with IX never overlaping.
