Please, please, please, correct "Mastery-Track Your Progress". It's impossible to see the criteria for completing "TIER2" before finishing "TIER1." Even though "TIER1" is complete and the steps have been accomplished, the software doesn't recognize the successes for "TIER2." Unfortunately, one must restart the challenges to obtain "TIER 2 MASTERY REWARDS." I could give several examples, but I believe one will suffice for understanding: "Oakville Subdivision": All scenarios have been completed and "TIER 1". Nevertheless, now I must accept the challenge to finish "Complete 2 Scenarios with a Difficulty of 3 or above" (redo the scenarios that have already been completed). Thank you, thank you, thank you for rectifying the situation. Furthermore, if you could indicate for all the routes how or where one can see the reward (precisely), it would be greatly appreciated. Example: I've activated 21 mastery rewards and have managed to see less than half. Keep up the good work!!
