Challenge specific settings
So, I've noticed that some challenges are either easy or extremely difficult up to impossible, depending on player gameplay settings.
Now this isn't necessarily bad, but for daily challenges, I would expect developers to set the difficulty, not players.
Take the 'endless kickflip' that massively benefits from certain assists, making it impossible for the 'experienced' profile.
Or take this 'Good luck' daily challenge, that is nearly impossible if the allowed fall height is set too low. And also benefits from other settings to make it easier.
There are some physics inconsistencies that really show during these challenges too. Succesfully cavemanning onto the roof and then just losing all speed immediately, per example.
But I also noticed that I've done this challenge before, and I was able to fly up way higher than I was able to now. So there are a lot of settings that are impacting performance in the challenge and making this one impossible.
