Whatever was changed regarding tile colors in the V22 update CHANGE IT BACK! When viewing tiles it causes severe eye pain affecting game play. I turned OFF the color blind mode in order to use default colors and restarted the game. The general game colors are the same as always so my assumption is it is something related to the color blind mode that affects the default mode.
Please fix it because I now have a serious headache from playing 3 titan Flags.
