R20 multi-instance bug

[4b4]

Just had a quick try in R20 with 200,000 cloned spheres onto a disc and it seems to have a bug.

Load scene, hit render, stop the render. Hit render again and you're prompted "The external renderer is calculating an image, do you wish to stop it" If you push yes C4D freezes.

There's no CPU activity in task manager.

Scene attached.

It also seems to have a very long preparing phase, approx 2:30 on this scene.

Cheers

Thanks for the file, I can confirm this is happening also, even on older builds of Cinema. Scene prep was only 7 secs here, same in R19.
