The Move tool offers us an option called Disjoin. When it is used Revit deletes the original and creates a new element at the new location. That isn’t obvious to us but if you examine the GUID (ID’s of Selection) you’ll find it has a new GUID after the Move is complete.
The option is sticky, we have to remember to disable it when we use the Move tool again. When we are working on sheets and adjusting views we now have an opportunity to run into a confusing error message.
If you run into this or people you support do, just remember to Disable da Disjoin.
