The map was updated on the server side to the current client version 18.104.22.168. You can find this client in the download section.
Please update your clients to this version so that you can see all items while playing and don't get stuck on invisible parts of the map.
By updating the client version, we have new options that we can use for future content.
At the moment there is nothing for you to discover, but of course we will keep you informed as soon as there is something new.
