Hey guys sorry to kinda highjack this thread but I have a question.

Have been checking thro the Decision in Russia mod and managed to install some missing art but something odd happened, no I don't have a problem the first turn opens everything looks OK.

For some reason I have two unit art files with the same name.
Only difference is one unit name is in black print ( new art file ), and the other one is in blue print, but this original game file is also a bigger picture.

Don't want to delete the original file, as I've never had this problem before, any clue as to what has transpired.
