New clues for story investigations appear only once a day.The rest (secondary) tasks are updated every 6 hours. These tasks have a timer in common with the supply chest, that is, the time can be accelerated in exchange for coins. And even if the timer has expired, then, in order to get new secondary tasks, the chest still needs to be opened on the “Supply” tab. This timer affects only secondary tasks, investigation clues are updated only once a day, regardless of the timer.At first, only one investigation is available, each following one opens at the beginning of each new week of the season.
