I get:
[SM] You do not have access to this command.
When my steam has the following flags (I use admins_simple.ini because, well... it's simple
):
"STEAM_0:0:266" "99:abcdeghijklnopqrst" //TnTSCS
Are you giving your admins the "m" flag by chance? They could be doing
sm_rcon sm_slay playerName to slay people
