Character keep getting stuck at the door. and start to jitter sometimes. Then fall off the terrain. Any idea why this is happening?
Collider size set to 0.4 and max step height is 0.35

Edit: This is not just happening with the doors, Walls are the same. Character get stuck in walls and then fall off the terrain.

You should check the mesh of your barn/house. There might be some normals pointing in the wrong direction.
