AI Move Stuck in some strange place

Hello.
When I use RichAI and Navmesh to find my way around a mobile device, the character always gets stuck in some strange place.
But I can’t reproduce that on a PC platform.

The character stays stuck in this position and doesn’t move in the other direction.

That’s odd.
Do you think you can post a video of this happening?
