I have 2 plant schedules - one with 'enitre plant' palette and one with currently placed plants.
I am also using work areas from 2 different xrefs. Numbers are updating fine after xref changes, so it generally seems to be working.

When I go to regenerate (all) existing shedules however, the 'entire palette' schedule becomes huge.
If I then regenerate only the huge schedule, it resizes back to correct scale.
