Is there any reason that a hole would move from roof/floor/area mode to drawing mode. This happens 100% of the time for us.
Yep, there's definitely a reason. I can venture just an idea as to what that reason might be: visibilities, maybe. In visible items menu, check drawing mode visibilities to see if there are objects from other modes set to be visible in drawing mode. Let us know if it works.
Visibilities was the first thing I checked. However I'm not sure what a hole would be classified as. I'm not sure this is a visibility issue. It seems to be a physical migration from one mode to another. The offending hole usually crosses a wall and possibly the edge of the shaded polygon. My shaded polygons are all turned off for cleanup. I have a few sample holes I am currently tracking to see when they migrate.
Damon, if you will upload a drawing file that has the holes you are talking about perhaps someone will have an answer. Right now I don't know exactly what you are talking about.

Here is a sample. i had to wait until it happened again. The hole is located at the front boxout.
Damon, you have a dozen or so different versions of this plan all segregated out with Building Options. I would need your Project file that goes along with this drawing before I could even begin to make heads or tails of what is going on here.
