A new bug has been discovered in Rhino 9 SR0 (2025-11-18, Rhino WIP 9.0.25322.06305) in Today's update,that causes all objects in the Rhino viewport to disappear , as if the file contained no geometry at all.
Not seeing that…
Can we get a little more information? What commands were you using? Was it all just drawing curves or were you creating other geometry types? Can you reproduce it? I saw a similar issue with meshes and subobject selection yesterday but it was patched before the WIP.
Tested in Cuve Geometry and…
If you have a way to repeat this, please let us know. This is pretty bad…
I just experienced this!
I have been creating tangent circles to the bunch of lines and, suddenly, everything is gone. Not a single curve, point or surface (there were plenty of them). I lost everything…. terrifying.
It wasn’t 3, but 30 minutes, but still…
On the side note: recovery from autosave was successful, but I’m moving back to V7.
@Piotr Do you have any recollection of the things you have been doing? Just drawing lines and circles, or is there more? If this happens again, pls run CommandHistory and post the results.
Did you experience this in the latest WIP? the result of _SystemInfo is highly appreciated.
Also: did things disappear when Rhino was idle or did it disappear when you were executing a command?

I was in the middle of the command when it happened.
I can’t provide any CommandHistory as the system crashed (luckily, which led to autosave & recover).
Yes, I have the latest WiP.
Thanks,
By any change do you know which? or maybe a couple candidates?
did any crash report come up? these are helpful to get as well.
No crash report was created. or at least, there is nothing I can find.
Ok. We think we know what’s going on. An outage with GitHub yesterday led to us releasing the wrong WIP.
We are trying to get a good one out now.
Done - there is a new WIP up now.
Btw - if this happens in the command history is the most useful thing to post.
The bug still persists: if you edit a Box(PolySurface) usingSubObject(Control Point)selection and then perform an Undo, Rhino will hang and freeze.(Crash)
Thank you! That’s a different bug, but yes - I’ll get that fixed and get a new build to you asap.
