Only one special building per barnony - is this intentional or a bug?

[Łabądź]

As in title I think that every barony can have only one special building/slot and it cannot be changed or replaced. I knew that if you build hall of heroes you cannot build Grand Temple or Golden gate of Kyiev. It turns out that the same is for other special bulding - I took the Empower the Sicilian Parliament decision and build parlament bulding in Neapol and now I cannot build University there (screen attached) - there is also no wording in University decicion that there cannot be a special bulding already there, there are only two conditions -40 development and high level of fame which I both met... I assume the same would happen if you took the Glass Monument building decesion but never got there.

Is this intentional to prevent baronies having more than one special buildg or a bug?

It has been reported as a bug and confirmed several times so my guess is that they know and plan to change it but other things are taking priority right now. But it is just a guess.

eta: guess I was remembering wrong, the Golden Gate conflict has been confirmed but not the one in Sicily. But I would hope if the former is considered a bug that the latter also would be.
