ERROR when "use primitives" enabled on Light tag

Hello, I noticed that there's a "use primitives" check box in light tags, and when I enable this, it seems that octane gets extremely enusable. eg. I would move my light with Live Viewer up and running, and then I would get an instant failure with the log saying this:

*******
Started logging on 29.04.20 11:38:03

OctaneRender Studio 2020.1 (8010000)

CUDA error 700 on device 0: an illegal memory access was encountered
-> failed to wait for event
device 0: path tracing kernel failed
*******
(You can easily recreate this with just a normal light in C4D, and also run the live viewer.
I also have the latest studio driver according to Nvidia Geforce Experience app)
Am I using the "use primitives" wrong? what should I do? Thanks!

Hi,
no problems here with Primitives Lights, in both Rectangular and Sphere mode, the lights are moving correctly in LV:

Could you share an example scene that shows the issue?

Hello! Thanks for replying!
After some messing arround I found that the bug is only recreatable when RTX on is enabled and moving lights with use primitives checked in a relatively larger or complex scene.
I've uploaded the c4d file that gave me trouble.
Please check it out, I have RTX on enabled, and when I try to move the lights under group "Type" null, which have use primitives checked, I get instant failure every time. Does it happen to your machine as well? Please let me know and thank you!
