Just wondering why in all kano games there is a timer for adventures that tells the player when it renews but challenges does not have one? A challenge timer would be nice to let you when they renew too.
probably because there is a maximum for jobs that you can assist on for a 22 hour period. there is no cap on challenge helps. but the xp for challenge helps goes down to 1 xp if you help on "too many" of them within a 24 hour period.
Like Jarvin says, there is no limit but a timer when it resets to max. XP would indeed be nice. Maybe it resets at new gamer day? I never payed attention to it.
This is actually a cool idea, I'd hate to help on 20 challenges for crap exp if it was going to reset to max a min or 2 later
