@PaddleStroke i know you're busy, Would you have a moment to weigh-in on this ? TIA 🙏

[PaddleStroke]

I don't know this part of the code so I wouldn't be very helpful.

However what I can say is that this 'duplicate object' command is wrong on a UI standpoint. We should be able to do simple copy paste of object.
By the way if you do copy paste you don't have the same error message as the duplicate command.

I don't understand the point of this duplicate command. And copy paste works (even though the copy paste is needlessly complex with the dependency window). It should probably be removed imo.
