Hello,
JMM has made further developments in order to integrate the modds to the standard installation, with no "injury" for the installation of the game. Our modd for the Waterloo Campaign will work in this way : all the files of the modd will be added in some folders of the installation of the game, but not replace existing files. So the modds installation will be neutral.
The Peninsular War Modd was done before these developments, so it works differently. An adjustment would be necessary in order to adapt the PWModd to the new system and also to make this modd neutral for the installation of the game. Like you Franciscus, I hope this will be done because it is a modd of high quality, and the PWM team has done a lot of work for it.
Best regards, and happy new year !!
