Hatz can’t pick up items too close to it

I went to eat salt rocks at hotsprings and accidentally let a salt rock fall instead of clicking to eat it. I noticed that it showed me the option to pick it up and did the animation, but it wouldn’t pick it up till I took a step back.

Showing the picking up option but not doing it (only animation)

As soon as the option appears it should be able to pick it up, since the animation worked too
