So tonight I start working on paving my longhouses on top a 300 slope dirt wall. I have a long wood bridge to get up here for the construction. After paving the planned floors I drove the wagon out the door which promptly fell through the bridge and had to be driven down the dirt wall, once at the bottom the wagon dropped to the ground level. After driving back up to the top of the bridge I discovered it was no longer possible to enter the building and on attempting to do so would drop the wagon through the bridge each time. I tried it several times, while pondering this Enki was on hand to deliver my auction bricks and I asked him to bash out the first tile in front of the door, he was there when I first dropped the wagon through the bridge so knew first hand there was a problem with this. After removing the first paved planned tile the bridge was once again operational and no more incidents.
