Hello there,
I'll be patient but i have this bug since a week or more, me too.
Citizens are free and the University is broken. It shows 1d11 remaining at each research and that i can finish for free, but it really cost 300 crowns. I can also abort and be half refund, it works then stuck again if i start another.
For now, i have 5 researches at the University that cannot be finished.
I like the game, thanks for the good work
