I have a strange bug going on in the college of winterhold in which all the trainers and traders (tolfdere, etc) are not offering their trade conversation option (ever--irrespective of time of day/location), however they do offer their training services. This is especially problematic as it is difficult to acquire the higher level spells (not impossible as I have a mod that adds a few additional vendors with the more advanced spells list, but still irritating). I suspect this may have been caused by a glitch that occurred during the warding demonstration in the beginning of the quest-line. He would hit my ward and act as though I had dropped it before he cast. Eventually I just used the console command to advance the quest. I worry that this may have caused the error. Has anyone experienced this, or know a console command (or other means) that will fix this issue?

Thank you
