Short description of error
Works fine in previous versions, but the same file in the test build for 2.70 makes the wheels jump continuously
Exact steps for others to reproduce the error
add a 'Cube' add 4 Cylinders to use has wheels, rotate and aply rotation, make the apropriate logic brick to use the script(you may use the one provided in the blend file, add a 'plane' to use has a ground, change to game engine, set wheels to 'no collision' in the physics panel, the 'cube' to 'rigidbody'. Press 'p'. The 'vehicle should fall to the plane and stop. The behaviour seen in the newer version is that the wheels don't stop jumping.
Note: this behaviour happens with other values with different configurations(meshes, mass, sizes, etc)
I'm just providing this file has a test of the problem. Not sure if this is a bug or some change was made to the game engine physics to correct previous bugs and now this is the new expected behavior.
More instructions are in the blend file attached.
