Инициализация массива, выполняющая, казалось бы, не связанные классы C ++ SDL

Итак, я почти закончил писать свой первый крестик на C ++ и SDL, и у меня возникла небольшая проблема. Я использую конечный автомат для переключения с титульного экрана на экран выбора формы, для проигрывания одного или двух на экран выбора выигрыша и обратно на экран выбора и т. Д. И т. Д. На экране выбора у меня есть два массива SDL_Rect, которые действуют как кнопки, а кнопки — это кнопки. Спрайты X и O, которые я использую на своем листе спрайтов. Когда мышь наводит на них курсор, они меняют цвета. Все хорошо и модно, пока игра не вернется к экрану выбора после проигрыша или ничьей. Когда он возвращается к экрану выбора и мышь наводит курсор на кнопку, на ней не отображается выделенный спрайт мыши или указатель мыши, который он обрезал ранее. Я указал, что эта проблема связана с инициализацией моей функции set_grid_regions (). Но этот массив никак не взаимодействует с классом экрана выбора. Как это может повлиять на мои парящие спрайты?

Так что каждый может видеть, вот вся программа:
