My content manager shows EGLC London City Upgrade but I never bought it on marketplace. I only bought V1. That’s the big bug, it shows for everyone even though it’s never been for sale and none of us have bought it. You can’t install it and nor can we, because it’s never been for sale. I know this because I was watching the marketplace release announcements and the marketplace itself every week, and the Orbx discord as well, because I was really keen to buy this.
See this thread for the workaround to reinstall V1 through marketplace.
