I'm having trouble drawing background after using text/drawing commands from drawing.h.

After drawing the score and some lines to the screen when I try to load the background for the win/lose screen it looks glitchy and weird. I know it's something to do with using the drawing functions in drawing.h in conjunction with the background?



    if (enemy_score != player_score) {
        wait_vbl_done();
        HIDE_BKG;
        set_bkg_data(0,212, &win_data);
        set_bkg_tiles(0,0,20,18,&win_map);
        HIDE_SPRITES;
        SHOW_BKG;
        waitpad(J_START);
        waitpadup();
    }
    else {
        wait_vbl_done();
        HIDE_BKG;
        set_bkg_data(0,180, &lose_data);
        set_bkg_tiles(0,0,20,18,&lose_map);
        HIDE_SPRITES;
        SHOW_BKG;
        waitpad(J_START);
        waitpadup();
    }
