I encountered same problem on my distant linux server but not in LAN test server under Windows.
This problem only affected bots and not real players.
Some bots had UnnamedPlayer name, others duplicated several time the same name.
To avoid this double trouble, I reduced the bots number to 15 instead of previous 40 in the bots.txt file and I assigned a single name for all bots (FS~Bot)
1fx uses a diffirent command and goes regarding their minimum level restriction.
seta g_followEnemy "1" Checks wether clients are allowed to follow enemies while dead.
seta g_adminSpec "4" will make admins of level 4 able to ghost the enemy while being dead. (if im not wrong level 4 is S-admin)
Sorry but these CVAR are only useful in CTF gametype, and not efficient in DM
Miche was speaking about real Ghost mode wich could be launched by a dead Admin by typing "WALK" button in the old Rocmod mode.
Ghost mode is verry useful for discreetly spying a suspicious player, better than spectator status
