Thank you! About the nationes, you probably know that the decree of Kutná Hora, which gave the Bohemian nation as many votes as the other nationes combined in the university councils, was responsible for the leaving of almost all of the foreign students and staff at one point. I thought that if things were kept this way, it might be too unrealistic to expect many foreigners to return. On the other hand, if the Bohemian nation would be given only one vote again, there would be a danger of Papists conspiring against us. Apparently, many universities in Europe during the time had a similar system with a division into nationes, but not all, so I figured that just abolishing it would be an easy way out.
(Not completely sure about plausibility, but why not?)
