Didn't want to post this in the bug thread in case its a feature I'm not aware of. I recently started a game as a PR on Casual for the first time to see how playing PR went. About 10-12 days in I sieged a castle (the one directly north of Veluca, between the mountains and forest) and immediately after I got a message that 200,000 was taken from me. I only had about 30k before this and after the battle I was down to broke. If that is a bug I can try to reproduce it for you.
