There seems to be an issue with the VP shown. The bot's VP were around 45 at one time, and shortly after it they were down to 35 or so.
Game was 5478 I think.
That was probably due to a landmark. Scores can change dramatically on a single turn. For example, if Fountain is in the kingdom you will gain 15 points when you gain your 10th copper, and then you'll lose them again if you trash a copper when you have only 10.
The bot is also known to sometimes trash provinces, which could decrease its VP.
I had no landmark in play.
Maybe the bot trashed a province, have to keep an eye for that.
