I cannot remember now what happened if a city or road with follower plus builder losses the follower by the dragon, what happenes to the builder? (same applies if a princess removes the knight and the builder is in the city) Last online game the builder remained in the city and was used to score it, but guess that may not happen on the last version of the rules.
elendaleranda: Cheers. Also: The rules state that if the dragon lands on a tile that has a knight on it and a builder / pig in the same feature (i.e. city / road / farm) the builder is also returned to its player. That's why I asked this question the rules do not tell you what to do if there is more than one meeple within that feature, Gwommy answers that.
Gwommy: Cheers.
