I think the story was that there were 2-3 seminarians per room in Winona I don't know if that was really the case. Some may get along well like that, but I imagine many people seeking to become a priest would prefer their own room for the silence and lack of distraction. I thought the new building would have 120 seminarian rooms because it is the limit placed on the max number of seminarians under one rector, but I don't think there's 120, barely 100 at best.
The 2 ordained this year entered at around the time that the move took place. The move was too early, so there was much work to finish making the place livable while they were living there. That would have been hard on some seminarians causing them to either take a year or 2 off, or wait to enter, or otherwise not persevere in that vocation.
