I experienced a bug with the rats quest. I went to kill the rats (actually i fought a spider), and then brought the dead rat back to the house. When I arrived, I received an offer whether I wanted a maul, 300 gold, or 20 diplomatic capital. I took the maul, but then received the same offer again, and took the maul, and then received the same offer again and took the money. Thats when it stopped, however, the next turn I received the same offer again, and the next turn again. I also received all the materials, 2 mauls, some money and some dip capital.
