Thanks for the feedback. They shouldn't be different as they are prefabs, but maybe the physics affect them differently :)
Thanks for the feedback! :D
You're right, I misspoke slightly - the problem is not that they are not the same (they are), the problem is that they are not symmetrical. So the physics when moving them to the left are different than when moving to the right. But the movement you're doing with them is often symmetrical, so they effectively end up handling differently. It's a bit confusing, but I think the image I posted illustrates that pretty well.
