Using a mouse, the pillars in Tenet Chapel 2F have a significantly larger hitbox than is required for the quest to fix the pillars. There are some of the pillar fragments that are behind the pillars and I seem unable to click on them because of the fact that the pillars are obstructing their gathering. The fragments themselves are visible because the pillars turn invisible when going behind them but the hit/interaction boxes are still there.
A solution to this would be to have only the hit/interaction boxes be near the base of the pillar seeing as how you are supposed to stand near them to repair them anyways.
