Timer werden endlos ausgeführt

Hey,

wieso werden meine Timer ausgeführt und hören nichtmehr auf?

derby = SetTimer("DerbyEnd",500,true);

public DerbyEnd(playerid)
{
if(DerbyPlayers == 1 && At[Derby] > 1) {
SendClientMessageToAll(Gelb,"DERBY END");
SetTimer("NewRound",3000,false);
SetPlayerCameraPos(playerid,0,0,40);
return 1;
}
if(DerbyPlayers == 0 && At[Derby] == 1) {
SendClientMessageToAll(Gelb,"DERBY END");
SetTimer("NewRound",3000,false);
SetPlayerCameraPos(playerid,0,0,40);
return 1;
}
return 1;
}

public NewRound()
{
for(new i=0; i<MAX_PLAYERS; i++)
{
if(InGame[i][Derby] == 1)
{
NeueRunde(i);
SetCameraBehindPlayer(i);
SetPlayerHealth(i, 100);
}
}
return 1;
}

stock NeueRunde(playerid)
{
for(new i=0; i<sizeof(dcrosscar); i++)
{
if(FreeDPlace[i] != -1) continue;
else {
dcrosscar[i][vehid] = CreateVehicle(dcrosscar[i][modelid],dcrosscar[i][SpawnX],dcrosscar[i][SpawnY],dcrosscar[i][SpawnZ],dcrosscar[i][SpawnA],-1,-1,-1);
DCar[playerid] = dcrosscar[i][vehid];
SetPlayerVirtualWorld(playerid,1);
SetVehicleVirtualWorld(dcrosscar[i][vehid],1);
PlayersPlace[playerid] = i;
getZ = SetTimer("GetZ",500,true);
derby = SetTimer("DerbyEnd",500,true);
DerbyPlayers++;
SetCameraBehindPlayer(playerid);
PutPlayerInVehicle(playerid,dcrosscar[i][vehid],0); break;
}
}
}

Aber GetZ soll ja endlos ausgeführt werden, damit man stirbt, wenn man ins Wasser fällt
//EDIT

Zum Beispiel der Stock NeueRunde wird endlos ausgeführt
und der Timer: DerbyEnd schreibt permanent: DERBY END
