Your assumption seems correct to me, Davide.I think matrix patch 1.03 for the normal edition should include 1.02 but is missing something.
This one...
http://ftp.matrixgames.com/pub/ScourgeO ... p-v102.zip
... including both 1.01 (SOWWLPatch3.exe) and 1.02 (Master Patch.zip), and installed before v103, made it for my normal edition.
The most noticeable missing files, otherwise, were Hannover flags, as reported by RB.
It still shows v1.0106 on the initial MP screen, though.
But I think it's ok anyway?
