I am all new to the HWA forum so I don't know if this is the right place to post this. I was experimenting with the Physics extension and I was using hwa to smooth some rotations. The problem is that in some parts of the frame it runs fine but then all the objects dissapear and they are overlapped by a giant object. I realised that the giant object is a 'Physic' object. I will upload an example.
