For some reason I couldn't open your save.Hi and thanks for the Christmas update!
I was playing Byzantine and the empire collapsed. I thought the UP would protect me from it?
For the Round Church, I found it to be a severe penalty? If you intentionnally put -3 diplomatic penalty, maybe the description could be adjusted, because it currently mentions a small penalty. Maybe it could be also proportionate to faith, just as a positive bonus for sharing religion would be?
Thanks for all your work on this!
Nevertheless found a bug connected to the Byzantine UP, it might be the cause for your collapse.
The Round Church penalty should be lower.
In most cases it works ok in my experience.
Anyway, will check that too. It would be great to have a savegame, right before it's completed. In a game where it causes 3+ diplo penalty.
