Jedi Fallen Order kept doing this with its healing animation. That and like grabbing a zip line are dependant on the animation of your little droid and sometimes he's off doing something else so it won't actually heal you or let you grab a zipline.

But even more annoying is when it starts the animation of the robot tossing you a stim, and your character catching it and then... You lose a stim but don't actually heal. 😬
