You could avoid such situations simply by turning them off when player disconnect
A timer for example

pawn Код:

forward Timer(playerid);
public Timer(playerid)
{
if(!IsPlayerConnected(playerid))return KillTimer(YourTimer);
}

For PVars i think they get set to false when player disconnects but anyways you could use

pawn Код:

public OnPlayerDisconnect(playerid)
{
SetPVarInt(playerid, "MyVar", 0);
//.......
