The White players tower icon blends perfectly with the Bridge graphics because they are the same color. It's really bad on a North/South bridge because a White tower placed at the top/bottom is invisible because of the coloring.
This has caused me more than once to 'run into' a tower placed on a bridge without realizing it's there. I know the game can 'stop' movement before attacking but by then it's too late because you've used up your movement. I've even double clicked twice thinking there was a server timeout and ended up suiciding my armies into the tower.
Is it possible to have either the bridge or white tower icon color changed so it's easier to see. It probably makes more sense to re-color the bridge graphics to a dark grey color.
