What did you expect to happen when you stalled the airplane?

I expect it to lose altitude rapidly. Beyond that, it depends on the
design of the aircraft.

Well, in the category of "beyond that", in light aircraft the rapid
altitude loss is usually preceded and/or accompanied by an abrupt pitch
down. One caveat: there may be some newer light craft designs that don't
pitch too abruptly. I don't know about that. But in the great bulk of
light aircraft, such as the Baron you were discussing, there will be a nose
drop. I don't think you're dealing with a major design flaw in your sim
program, perhaps just a question of degree or intensity.
