Someone told me that we didn't need to book flights anymore (I am returning player) my fighter just made auto flight for his fight and is now devoid of energy and money, as a result he has been kicked out of his gym.
Sorry for complaining but there are so many majorly annoying things in this game and I am reminded why I quit last time. There are just too many small and pointlessly frustrating things to remember to do, especially when having a bigger stable of fighters.
