The copy and paste procedure gets different results in 2.1.3 and 2.2.0, as I just have found out. With this drawing, with 2.1.3 as Lambertus, with 2.2.0 as Gary.
I have suggested to try this method as in a test, where I had imported one block from the Library Browser several times, it worked. I thought it might be something similar with Lambertus' drawing.
Now I have tested if copying a block within a drawing really creates a new block in the block list - yes it does. Really dangerous. You have to know. It only happens with Copy and Paste, but not with the Modify - Move/Copy command.
We should check if this is common behavior in other CAD packages, standard. If not this should be changed, as it probably often produces mischief.
