Hi!
With as little spoilers as possible, I'm going to describe this infinite gold exploit. I feel like it might even be intended in a way, I have to imagine I'll hit a wall eventually. Please report the post if this isn't where it goes, or remove it if it shouldn't be posted.
When you get to a certain point where you have to chase a chicken in a contest, you can rig the track by dragging objects and rotating them to only give the chicken one path. Every race you win is 75 gold. I've done it about 5 times now with no signs of the NPC stopping. The only reason I feel like it is intended is because the crates in the race area are the only things moveable within the keep. Everything else flags you as stealing.
Thanks!
EDIT:
Eventually an event happens that stops the gold from flowing. Good padding while you can.
