EDIT: I created this bug report because i thought i had some missing Zandvoort layouts. I just realized it's split in 3 parts. Resubscribing doesn't fix it.
Maybe I should add that I was using a rather fresh install, only contents from the Workshop, on a Linux machine using Steam Play. Possibly that could also influence how rF2 is working....
Since I am not the only one who also has 3 different entries of Zandvoort 0.34 with different layouts in the list. I already wondered.
Have a look in game at the Select Track page. Take note of any tracks that are not in alphabetical order. Exit game and start the Launcher and uninstall those tracks that were not in alphabetical order, or unsubscribe if they were from the workshop. Start game and see if everything is back to normal.
Mine had Zolder (workshop item) in between the two Zandvoort layouts.....unsubscribed to Zolder, all good only one Zandvoort........re-subscribed to Zolder and back to two Zandvoorts.
I've now got three Zandvoorts ?? The first one is in place of Bathurst and Bathurst is down in the Z area !! lol
Bloody dyslexic game. Shouldn't be surprised, after all it doesn't even know a capital letter is the first letter of a word, not the second.
