Well I need help I don't know what to do recently after playing for like 20min, when I click on my city the hexagons well the terrain have like a red and white checkered color to them. When a great person appears sometimes their little picture is blocked by a red color. Furthermore around this time the leaders screen appears to be buggy their video or scene do not appear but I can hear their voices. I can do everything just that I will see the background of what I was last doing in the game instead of their screen.
