When normal towers are placed on modifier tiles, the type of modifier is still visible in the lower left corner of the tile. But when placing eg a Bounty modifier on these tiles, the type of modifier is no longer visible. It would be good to have this visible still.

Eg if I have a bunch of Bounty modifiers placed and want to remove one, I might prefer to free up a modifier tile to place an attack tower, but would not know where these tiles were if the Bounty ones were covering them!
