The granting of random Uni credits (not coming from the Uni entrance exam) and degrees sounds more like something EA's story progression does. I have to say that I have never seen this first-hand using NRaas SP. But DebugEnabler can be used to take the unearned academic credentials away, so can MasterController I think. And, in case it matters, sims can work towards and have more than one degree in different majors.
Traveler doesn't go around killing cats on a routine basis, we would have to see the script error log to be able to help figure out what might possibly have been going on there. The main purpose of Traveler is to quietly redo the world travel sequences with one that is more flexible, far less prone to errors, and allow worlds that are not WA, Uni, or Oasis to be travel destinations and to be linked within the same ongoing saved game.
