Not sure if this is a solo issue or just affects players grouped in parties, but when selecting a random hopper—say, the featured 20th NSX vs 350Z one—at any given track, it will instead load up Suzuka (I think Suzuka East specifically), then lock out your lobby menu and immediately disconnecting you.
Has forced several party regroups and caused a lot of frustration.
Seems to have started in the past week.
