On this beautiful morning I was playing with our dearest friend in quarantine times: Lord Rattington.
As can be seen in the "log banish.png" attachment, I played 2 "lost cities" and drew 3 provinces with them.
I then bought banish and clicked on the 3 provinces in my hand.
In the log it said only one province was exiled. I thought banish would have exiled all 3 provinces?
When I hovered over my name I just saw one province. (exile banish province.png)
