Alright; I'm done compiling the navmap data files for the latest update, and they're currently being uploaded to the web server. I'd say that we've got an ETA of approximately an hour or so - I'll update this post as soon as it's up and running.
EDIT [09:34 UTC+0 20.04.2017]: Should be all good now! You may have to do a good old Ctrl + F5 to see the changes, though.
