Sorry if this has been posted before. I noticed that the workers constructs buildings or, in this case, paths across different levels which is no bug but probably not intended since it could lead to abuse. In my case the workers built paths on a higher level/cliff from below instead of going up to be on the same level as the path/construction. I did not check whether it works the other way round! PS: Thanks for the demo, reminded me of one of my most favorite games, knights and merchants!
