Quote - "Maybe you had in your preferences Offset duplicated objects enabled, this looks like you scatter an object instead of duplicate it."

I think I know Vue enough to tell the difference. 
Besides, there's no much possibility for a mistake like that when I press duplicate once and I get 40 objects in a row.

Quote - "I use Copy paste Ctrl+C Ctrl+V. So I can duplicate many objects in seconds."

Why use two keys if I can use only one? Ctrl+D is duplicate. I admit I didn't use ctrl+c ctrl+v, have to try that, maybe the bug doesn't manifest that way, thanks.
