Napoleon's campaigns crash on the 1805 option, and work on the other options ( Regimental battles, Classic battles etc) but no units can be recruited and no info is shown for cities.
Napoleon's Campaigns were never included in our NTW3 SP Campaign mods, only the 1805 main campaign was done ~Lord Davn
The NTW3 v7.5 mod was released in October and updated on December 17th with the v7.6 patch
