Well, I am sure a complete re-installation of M2TW would fix this, but I don't want to go through hours of that if I don't have to.
My issue is that, in the Campaign, I no longer see the settlement names under them unless I hover the mouse over it. Instead, I see the names of all generals, diplomatcs etc. below them. This is very jumbled, since there are so many more units like this instead of cities.
If anyone knows why the game is doing this, please let me know! It was fine the first day after I installed the game, but now it has started doing this for some reason beyond me...
