Problems with a *.tag file!

[The Capo]

I am having a bit of difficulty getting the GameFont.tga and the GameFont_75.tga files to work the way I need them too. I added the Just Another Religion Mod to the Mod I am working on and some of the new religion symbols don't show up properly. This is my third attempt at editing it right and everytime I've tried it I've had different results but with basically the same two logos. Here is a comparison of the ORIGINAL artwork from the JARM and the artwork I am using in my game. The third picture is an example of part of the problem. This city founded Zoroastrianism and what shows up are the three symbols seen in the picture. I don't know much about editing graphics or modding in general so it may be something simple I am failing to recognize, so ANY suggestions would be greatly appreciated.

The gamefont file is very sensible when it comes to boarders between icons - getting that pink colour just one bit off the defined one, will cause the game to not recognize boarders and hence skip the icons. It is even worse on the alpha chanel, where you dont see the boarders - but they are as important as the pink ones.

When editing (copy/paste, painting or even worse using filters) Photoshop will apply some anti aliasing - this cause neighbour pixels, which you think you did not even touch to deviate in colour slighly.

What i believe to be the best is to prepare the icon in a separate file of exactly the right size (21x20 / 16x16) and then paste it into the gamefont, making sure the anti-aliasing is diabled in PS while pasting.
