iOS Collision isssue

[eisen]

When i test my game on unity editor obi fluid object collide with ground but when i build a game and test my iphone passes through collider. I tried with box and mesh collider but the result is same. How can i solve that ?

Update: When i instantiate object after game starts its not working. But if i put scene directly its working. But this problem only happening at iOS

Are you making sure that  when you instantiate an object, the phase of the collider is different than that of the fluid? Could be that.
