I missed this post!
What you report is very strange!
On previous AGEOD games (AACW and BoA i think) there was a game option that alowed you to chose betwen showing the leaders portrait or the on map counters or the portrait of one of the units of the stack.
That second option seems to be what you report.
But on NCP that option is not there anymore. Leaders on top are the default.
Still this can be changed by manually editing the general.opt file you find on
C:\Program files\Napoleon's Campaigns\NCP\Settings
Have you made some editing on that file?
Mayeb you changed that by mistake...
You can open the file with notepad and check how its set now. Look for this lines
6. *** Display options ***
LeaderOnTop = 1
If instead of a 1 you have a 0 on that line i bet the units will show instead of the leaders. I
f this is the case, try to put a 1 back there, save changes and launch the game to see if it works
In any case it's very strange you have this problem without manually editing the file.
The patch did not caused problems like this on my installation. nd I have not seen any other similar reports...
Hope it helps anyway!
