yes I saw that about a week ago, and but I has the scale that I was working.
I did some wok on the joint when I added the ability for them to act as actuators, and I suspect that's when I added the bug. I will fix it. I though that it was related only to the hinge but now I see is on the base class. I will fix it.
yes I fixed this morning. I did not posted because I think there is still one more bug that I was debugin this morning. but I still had not found it. any way for you it all should be fine. try using the newton actuator2
CustomHingeActuator, CustomUniversalActuator, and CustomSliderActuator so that you cana see how cool they are for controlling stuff in a game. is it like animation but that obey physicas laws.
