I've recently started to have an issue with my schedules (all of them) where whenever I change an objects information (room materials, door types, whatever) my schedule will show all of the listed items, but the last line of the schedule will be removed from the main list and put off into it's own list off to the right. I can temporarily fix this by using the "restructure table" option from the pet palette. But, if change any of the objects again, back to right it goes. Does anyone out there have any ideas? I have attached an example of what I'm trying to explain (the problem is just visible on the upper right of the schedule).
