Hi, just discovered this great site whilst finally deciding to play online and getting ranked up. Spent the last couple of weeks doing my daily challenges and got to Major grade 1 yesterday (whoopheedoo I hear you cry) and thought I would try the Endure challenge to take me to grade 2 (only 10,000Cr needed) and the thought of 30K in one sitting was nice!
Received the challenge confirmation at the start of the 5th wave. Carried on until I got 1 million points and ended the game. To my frustration the credits have not been awarded and I am still stuck on grade 1, even though the challenge is showing as complete.
Any ideas please?
