Lunacy version: 11.5
OS version: Windows 11
Bug Description:
As shown in the video, when I’m on the second artboard and try to duplicate the grey square by holding the Alt key and dragging it, the new copy strangely appears on the first artboard instead.
This makes it completely impossible for me to work when using multiple artboards.
We’ve looked into this, but couldn’t reproduce the issue you’re experiencing on our systems.
To help us investigate, could you please check if this issue happens with only one specific document, or if you can reproduce it in a brand-new document as well? Please let us know the result, and if it’s a specific document, send it to us in a direct message so our team can study it and find the root cause 
I have a similar issue on version 11.6, also Windows 11.
In my case the problem appears when duplicating and moving an object while holding alt + shift.
The object appears on the first artboard instead of lining up with the first object that is being duplicated. (exactly the same as in the video)
This doesn’t happen if the object is moved inside the first artboard, or if the object is outside any artboard.
For me duplicating with holding only alt while duplicating works without the described issue.
Is this issue occurring with all documents, or just one specific document? If it’s limited to one, please send it to us via direct message or to support@icons8.com so we can investigate.
