Hi, I have some feedback/bugreport. It seems that some of the challenges only 'conclude' if they are closed with exactly the amount of fields or houses. Example, the village needs 2 houses, sometimes I can close it off with a set of 3 or 4 houses, sometimes it needs exactly two. It is unclear to me why this is. It seems to be coupled to the prevention of merging two larger sets to make an easy completion or preventing a new challenge directly being closed by adding it to a unit which already matches that challenge (for instance a 4 house tile which needs +34 houses and connecting it directly to a village with already 40 houses). Sometimes however, this merging of larger units does seem possible.

Could you tell me if this is a ''bug'' or part of the specific challenge?
