setWorldSize bug?

I found a bug, I think. The setWorldSize is not working corrently on the +z (positive z) region. The -z (negative z) is working, but not the other side. It looks to be infinite or something, because I kept shooting far as I can in the +z region.

This is from my code, I already tried both:

mWorld->setWorldSize(-Ogre::Vector3(0, 60, 100),Ogre::Vector3(4000, 1000, 100));

mWorld->setWorldSize(Ogre::AxisAlignedBox(-0, -60, -100, 4000, 100, 100));

i believe this was reported on the Newton forums, and should be fixed in the next version.
