While we are on the subject of the Abbey and Mayor expansion, in particular the wagon. Here is a question of my own (with pictured examples).

I have a wagon occupying a road.

I draw and lay a four way road tile with cloister seperating the roads.

I decide to play a farmer to this tile (don't ask "what is the point of playing the farmer", just bear with me

) The placement of the tile completes the road with my wagon on.

I score the road and roll my wagon onto the incomplete cloister. The tile now has 2 followers on it. Is this legal?
