Bets thing to get BSM 1.3 started:
1.UnOffical Patch 1.06 --->first unpack it in an empty folder and then paste the unpacked files into your GameDir (I will call that action "install" at the rest)
2.MapPack ---> "install"
3.BSM Pack ---> "install"
WARNING!!!
If you get an error message while executing the PatchMe.bat because of a missing dll-file, just repeat step 1. AND 3., nothing more, nothing less.
If you done so the Patchme.bat would be executed how it should be.
The thing that you cant reload your shotguns, watch this, its just a cutout but you'll see what I mean:
ITEM "USAS-12 (12ga)"
Class Shotgun
Caliber "12 caliber"
Weight 5620
PrepareTime 0.27
The line I highlighted has to look like this exactly otherwise the game wants you to reload the weapon with cocumbers or what ever
I guess in that line there stands somesthing like :
Caliber "12 calibre"
