Sadly enough I saw every episode but can't remember if anything was resolved or not. None of the changes improved the show. Kromags would have been ok a couple of times but they received too much air time. The Prof and Quinn were the best and I do think we switched professors. This was a neat idea but without the ability to introduce new worlds and races like they did on Stargate there was only so much that could be done with the premise. Once you accept the uncontrolled sliding you have a pretty hard time doing much in the way of story arcs which are the bread and butter of modern television.
