Howdy there,

Whenever a tile gets corrupted, it will have no visual effect on the main view or strategic map view.

Steps To Reproduce:

#1) Start/load game
#2) Play until a tile gets corrupted by an event, or spell.
#3) Use mouse hover tool tip to locate corrupted terrain.

Results 5/5:

A) The corrupted tile will not have any visual indication that it has been corrupted. (Other than the tooltip)

Note 1: Although the player can eventually locate and cleanse the tile, it tedious work to locate it hovering over each of the city tiles.

Note 2: This also occurs when attempting to view a corrupted tile via the Strategic Map View.
