[UnDetectable]

I don't really get it but I doubt that you have created

Код:

pInfo[playerid][DM] = 0;

in OnPlayerDisconnect before your timer

That means when the player disconnects, the DM info sets to 0
before your alive counter starts

So when the counter checks the player, it won't work because you are checking if the DM info sets to 1

Код:

pInfo[playerid][DM] && pInfo[i][DM] == 1

Which is not

Just guessing xd

And btw, why you are setting the health of the player to 0 when he disconnects? xD
