My apologies, looks like it'll be delayed for four-five hours at best due to some scheduled server maintenance which prevents me from uploading the patch right now (which is currently finished); again, I'll post in this thread as soon as I've got any updates for you.
Everything seems to have been working like it should after the map update and the web server migration this morning (thanks again, Alley!), so I'd say we're good to go for now; thank you for your patience! Note that you may have to hit Ctrl + F5 with the map open to bypass your browser's cache to see the update if the map menu still says "29.06" for you.
Minnesota was removed in v4.88.6 (i.e. the latest update), so this is working as intended. You can take a look a it by enabling the "Show inaccessible/oorp systems" option, as it's still in the game data.
Niévre Asteroid Field happens to exists on both the Burgundy and the Champagne maps, on the very same spot on both system maps, however it cannot be found in Champagne in-game.
