what is the command to update the server ?
I use a .bat file to update it. (In the spoiler)
Make a new text file then when you are done go "save as" and end it with .bat for example RO2 Updater.bat
You change the "./Red_Orchestra_2_Server" to whatever you server folder is called.
*NOTE* place this bat file in the folder before the server folder! Example: my structure is ...SteamCMD\Red_Orchestra_2_Server
Alternatively you could put the whole address in. Example: +force_install_dir E:\Program Files\SteamCMD\Red_Orchestra_2_Server
Hit me up with your server name when you update it please!
