The A9 update feels to me like the map taking on what may come to be something resembling its final layout- I think the Topside's main weakness right now is that the routes to point take a while to cycle between but I think this might be what the map is at this stage; because otherwise, I'm very happy with the layout as it currently is.
Changes are as follows;
-A new hallway between the Stairwells, with doors sectioning it off into two chunks. A third exit points towards the point
-More signage throughout
-Left stairwells have been updated to be smaller and slightly quicker to navigate through
-Scaffolding stairs have been replaced by a more obvious and permanent structure
-The vent that was previously close to the point has been moved to the storerooms on right-hand flank route.
-Aforementioned storerooms halved in internal size
-Rectangular structures next to point replaced with more visually appealing porta-cabins.
-Minor revisions made to the link buildings from Spawn to the Left Stairwell
