Why are the Caveman races only for 1 person, if I was able to get an achievement in 2. Let's even say that only for 1. Then I can add 1 icon, which is 1 player, since the number of players is not specified when submitting the application (you just can't add anyone but yourself). Or can I add a category like everywhere else for 2, 3-4, 5-8? If you fill in a video of everyone with confirmation that they were only with rocks, won't the race be considered completed? Thank you in advance for the answer.
