End Game Maps and Deadly Boss Map Bugs

Some maps on the end game map for some reason remain inaccessible even though a node that connects to the map is completed. The issue seems to be that the lines connecting the nodes are either incorrect or the bugged node doesn't recognise the completed node as a completed pre-requisite.

The lines between the nodes are sometimes not connected either with some maps looking like they're not connected to any other nodes.

There's also a bug with the deadly map bosses, where in new "indicators" that show the maps that need to be completed to unlock deadly map bosses either are wrong or just don't work. I have had multiple instances where I have completed the maps with the "indicators" on and the map still remains inaccessible, until I complete another nearby map without the indicator.

I feel like these two issues are related, as it seems the pre-requisite nodes either aren't connected properly, or not displayed correctly.
