visible in simulation ? (possible dForce bug)

Padone

I see I can animate the "visible in simulation" property. That is, if I switch it on and off in the timeline then it stays on and off where I keyframed it. But I also see that dForce seems to ignore these keyframes. That is, it only checks the "visible in simulation" property at the beginning of the animation. So if it changes dForce just ignores it.

This can be useful to do animation effects such as "grab and leave". I don't know if this is a bug or if I'm doing something wrong. Can anyone please check ?
