Hi and sorry about that.
Yes it sucks, but I don’t know where it’s coming from.
I might have a fix for next release but I’m not 100% sure as I could never reproduce the bug.
You can send the file at stephaneginier@gmail.com (the lz4 or zip is fine), and I should be able to recover the file if that’s the issue I’m thinking about.
Do you remember if you remember if you renamed your ne of the object in your scene?
