I registered an account just for this....
I have the same bug...
sorry I cant give you the screenshot...
In my case,
Dutch got 0 gold and -2200 gpt
Sejong of Korea got about 5000 gold with 1000 gpt
Isabella of Spain got about 10000 gold 1200 gpt
its just approximation... it just happened few hours ago and I started to search the bug info in the internet... I rage quited btw... I had leading score, but it just pissed me offf... always looking for a perfect win...
so my conclusion is the dutch gave 1000 gpt and 1200 gpt to the korean and spain... such an annoying bug...
I played few games before and didnt get this bug...
things that come to my consideration are (because I never did any of this in my previous games)
-I switched (all sejong's cities and his capital city + all isabella's cities but not the capital city) into my religion, (but they had their own religion)
-I switched all dutch cities into my religion (including the capital city) and they graciously accepted it to be their major religion..
