I always program defensively so when the change node got the deep copy option added - I always tick it

I only have a vague grasp of why this is necessary but I do it in the hope that one node won't affect the operation of another node in my flow

I'm just wondering if the move action should also have the deep copy option or is it totally unnecessary

This is all above my pay grade obviously but I thought I'd ask 🙂
