I noticed that the Shrine of Sysuul diagram shows 5 1x4 Dungeon Floor (AV-527) being used, although the set only comes with 4.

Maybe the next time someone builds them from the videos they could take a few pictures?

Another request for an update on this!

I wouldn't mind if the building guides were simpler if that was easier to produce. A set of diagrams seems much easier than having to watch a bunch of videos.
