This is the problem why your code won't work.

Wrong

pawn Код:

if( !IsPlayerConnected(playerid) ) return 0;

Right

pawn Код:

if( !IsPlayerConnected(playerid) ) return 1; //or if( !IsPlayerConnected(playerid) ) continue;

EDIT:Look at Konstantino First and to fix the IsPlayerConnected Problem, look at this one.
