Addition: unit id resets only if component has "All units are not interchangeable" unchecked.

[Felix Uhl (ifreilicht)]

This bug also exists for selecting multiple components as a Block and then using the "Copy Block"-command. I can confirm Sergeys addition that this bug is worked around by checking "All units are not interchangeable" for the component.

[Jeff Young (jeyjey)]

This is by design. If the units are interchangeable, then they're interchangeable. (We'll renumber them during annotation too.)

If you don't want that, mark them as not interchangeable. It's not a work-around; it's what that setting is for.
