-batchmode launch param not passing through properly

[ShizCalev]

I am having issues with launch commands not passing through properly, specifically -batchmode for numerous games.

Example vars/app;

set login=anonymous
set install_directory=C:\Servers\Blackwake
set exe_path=C:\Servers\blackwake\BlackwakeServer.exe -batchmode -nographics
set appid=423410
set update_appid=420290

nographics is going through fine, but no matter what, batchmode will not pass through with the script. Launching the app through a normal command line/shortcut with the switch results in the intended functionality.
