Any time I attempt to draw a product and there is an error or an invalid hardware item in the cell where a hardware name should be, AutoCAD crashes immediately (see attached image, which was on a HWR Array).  I've only noticed this on the past 2 releases.  Prior to them, I would get at least a generic error message.  I don't know what is supposed to happen when it attempts to draw (I would much prefer the error message come back), but this has caused me to lose work on more than one occasion.  It is also difficult to pinpoint the error, as there is no message saying where it originates from.
