All my daily tasks to get 100 Dino dna include doing some Campaign challenges. Since I’ve finished them all, I can’t complete the dailies anymore. Either add more or delete them from my task list. Seems like a waste of time when it’s impossible to complete them.
You can do them again and it will count, it doesn’t have to be one that isn’t completed, although I do agree that it should be changed for those who have already completed the whole campaign.
Just redo the easy early ones. You won’t get the rewards but you’ll get the daily benefit.
