i don't think this is the intended behaviour, a copied node should be unique, right? I'll try to add a gif that shows the problem not happening with adding complete on two copies of the node, and the deadline being applied to all even though they should be unique.

Whoops, I never replied to this. This is indeed undesirable and unintended behavior. I've found the bug and will be pushing out a build soon with a fix for this. Sorry about that, and thank you for your patience.

This is definitely resolved by now; thank you for reporting it, Skytrias.
