Hi,
I saw some days ago a FB post.... and I just have time 
.... and checked the update info on the FM page
New Circuit: Nurburgring GP
- 4 circuits
- Night lighting
I knew the following:
Nürburgring GP
Nürburgring Müllenbachschleife
Nürburgring Müllenbachschleife morning
Nürburgring Müllenbachschleife night
Nürburgring Sprint Strecke night
(actually can't remember all variants in the challenge.... but I think there was no additional one)
Looks like another typo...
