Ok, you lost me after packed strings part.. anyway, can the code below cause any side effects?
It seems to work great 
pawn Code:
new
gPlayerName[MAX_PLAYERS][MAX_PLAYER_NAME char];
//OnPlayerConnect
GetPlayerName(playerid, gPlayerName[playerid], MAX_PLAYER_NAME);
format(str, 64, "%s has joined the server.", gPlayerName[playerid]);
