BlockManager deleting entire scene

Rhino Rhino for Windows
1

Hi,

I’m having a rather odd issue with Rhino 6 and BlockManager.

Sometimes after updating blocks I will lose every single object in a scene except for lights. I’m able to undo the action, however it’s not ideal.

It’s difficult to reproduce the problem - but I have a strong feeling it has something to do with BlockManager and the update process.

Anyone else have this?

Sorry hadn’t noticed it was covered previously. I’ll install 6.5 and come back if it’s still occurring, thanks.
