I have  discount today on Wheel of Fortune for 55% on All Units . For some reason it will not let me use it ,im trying to buy 50 fireships as i always do on these discounts but it just keeps saying error everytime i do . ive tried reloading the game a number of times over the last 4 hours and even cleared my cache but still wont let me . Any ideas how i can get this sorted before the timer runs out?  My coords are x-725 y-345 on Gold Coast . Thank you.
