Which, if you reread my post, you will see is the exact same version I checked it on.

"devcommands" is an unlisted console command. It does not show up in the list when you issue "help".

If the console is spitting out "command is not valid in the current context" when you're trying "god"/"fly"/"debugmode"/"spawn"/any-other-advanced-commands, then you're either connected to a multiplayer server or you're not acually activating the advanced command set correctly (such as by issuing the unlisted "devcommands" command in the console).
