There are two+ bugs here.
#1 (so that it is clear that this is not merely an model bug) if i try to drive across the bridges below i get kicked from wagon and takes multiple tries to find right angle to get back on wagon.
#2 Bridges after a recent update are "sunk" by what looks like the thickness of a floor.
Old bridges have not changed it is only new bridges, this is the first time in over a month i have had time to seriously work on my new castle, As i have built a couple of these I hope that someone will help fix them and i guess i will hold off on all the other bridges,but this really sucks as i could get a lot further if not for this.
Left is old (pre bug), right is new
Left is new, right is old (pre bug)
new bridge section just complete (1x1)
After getting kicked of wagon trying to drive across bridge note the horses are sunk into the floor (this is third floor of my castle)
