A few options that could be the cause of the problem @DANDM ...
1. Most important one, are you logged in while playing the game?
2. Did you have a stable internet connection while achieving the Quest?
3. Do you have adblockers running? (They sometimes prevent Quests from unlocking)
4. Did you try logging into the website and load the game with another browser? (Some browsers cause trouble for a game to unlock the Quest properly)
5. Did you play in incognito mode?
And about the counting... if you are trying to achieve the 'Count to 100' Quest, that won't work... it is only achievable through the official Ct100 thread in the Forum Games section. Any other attempt on the Forums is considered spamming.
