Terrain with raw data collider problem

Unity Engine
1

Hey everyone,

I have an interesting problem with terrains. I am using a terrain which is created from a raw data and after upgrading from 5.0.1 to 5.1.1 my game objects suddenly started to sink from terrain and then pushed on terrain again.

Almost half of the object goes into terrain and then it appears on top of it. I couldn’t figure out what could be the problem. Because it was not happening before.

Any help will be appreciated!
Thank you.

Ok. I found something to work around but I still couldn’t figure out whats happening. I generated an .obj file from terrain data and add a mesh collider to it. Then I can use this mesh collider instead of my terrain’s collider. But why is this happening?

What am I doing wrong? Any ideas =/
