I am trying to join my friend's Garry's Mod server and Steam is telling me that Garry's Mod is trying to launch with optional parameters. I don't know why, and he is telling me that he does not know.
The code it is trying to run is:
+connect p2p:(a long string of numbers is here).
What does this mean exactly? Should I be concerned? As of now, I have not connected yet.
Update: I tried to join a friend's Borderlands 2 game and it gave me a similar thing.
It tried to run:
+connect_lobby (a long string of numbers)
Is Steam just displaying something it normally doesn't?
Update: It has stopped loading them up with optional parameters, or at least showing me that it has been.
