I have been working on a light plot, adding a bunch of information in, after changing some of my label legends when i refresh the instruments to see the changes some, not all, but some of my unit numbers get switched around. This seems to only happen on a couple select lighting positions, but it doesn't make a lot of sense. When i renumber the instruments back to what they should be the niext time i refresh the same thing happens. The thing that seems strange is that on;y the unit numbers change, all the other data associated with each instrument stays the same.
