The star finding algorithm seems to get confused when the frame is too far out of focus. I run into this problem when switching filters that are not para-focal. If the new filter is far enough away from the focus point, the first step of the re-focus will not back up enough, but if it backs up too much the a refocus of an existing filter will fail. The biggest problem seems to be that the algorithm for finding stars will trigger on the edge of an out-of focus star instead of the whole large round disc.
