We're seeing this message a lot with every updated model from the architect. What's causing this? Is this because they're deleting walls instead of moving them? We can't continue opening our model unless we delete the erroneous instances which in this case, totals 83 devices. Needless to say, it's giving our guys a lot of grief having to track down where the devices were deleted and then have to add them again.
Thanks!
