You have to do the Quali in ?anual mode I suppose?
People said super cars and weak opponents didn't work right in qualifying if you were in manual mode. I updated the trainer to help with that.
Only works for manual mode, yes. The trainer won't help with 'simulate'
Cannot replicate. Maybe you can contact 0x90. Sounds like something is preventing Aurora from accessing your game, like an anti virus or an anti malware or some program like that.
I suggest you deleted everything in your Aurora folder then redownload and make sure you extract all the files.
Also make sure the folder is excluded from your AV and that it isn't location on a cloud saving location like onedrive.
