PK3 files can't run in a batch file with the parameter skill

[doomexpert]

Hi, if i run stronghold.pk3 in a batch file with the parameters: ( gzdoom -file strnghld_v1.pk3 lights.pk3 brightmaps.pk3 -nomusic +set teamdamage 0.5 ) then i only have to click on the batch file to run and it works
but when i set -skill 4 after -nomusic like: ( -nomusic -skill 4 ) it crashes... but only with stronghold.pk3 so if i do the same with another pk3 file like paranoid.pk3 it doesn't crash, also when i set -skill 4 parameter in it and it's not the problem of a save file so the issue is stronghold.pk3 i think.

So later in the menu of stronghold you select new game - ultra violence as skill 4. you saved your progress then later you can instant load a saved file to edit the strnghld_v1 batch file you can add the parameter -loadgame save1.zds. then it's the same skill when i play a saved game of stronghold but i can't type it in the strnghld_v1 batch file, it crashes

i've upload it so you can test it but it will crash, you must move or delete the parameter -skill 4 in the strnghld_v1.batch file to able to play it. this is only a prove of example.
To play you have only to click on the strnghld_v1 batch file, to move the parameter, right click on the batch file to edit. and put this in the new gzdoom directory and download stronghold

So i want to know what the differents is why it do work with other pk3 files and why stronghold.pk3 doesn't work...

other pk3 files can run with a parameter -skill option. only strange that you have to select new game in the menu to able to play rather then instant play at level 1
