Bruto/yak passenger npcs getting knocked off because of Idol of Ohn'ara

Title. I used the new bruto just fine before accidentally activating the toy (they’re next to each other on the bar), and my vendor npcs are forcefully dismounted now with the Idol buff.

About three seconds after mounting either the yak or the new bruto (haven’t tried others, probably works the same), the NPCs fall off the mount. The animation is as if they’re just being dropped, for the bruto, like they’re falling from some height. The yak vendors just blip to the ground with no animation.

I confirmed that it’s the Idol of Ohn’ara, because it started in Deadwind Pass and continued in another zone until I turned off the Idol, and now it isn’t doing it. This is quite silly, and I was very concerned until I figured out the Idol was the problem.

In case anyone is curious, the Torch and Thinking Cap do not cause this, only the Idol.
