Replace your /spec off with this:

pawn Код:

if(!strcmp(params,"off",true)) 
{
  if(!Spec[playerid][Spectating]) return SendClientMessage(playerid,red,"[ERROR]: You should be watchful."); //wtf?
  SendCommandMessageToAdmins(playerid,"SPEC OFF");
  TogglePlayerSpectating(playerid, false);
  return SendClientMessage(playerid,yellow,"You left the observer mode.");
}

And move SetPlayerInterior(playerid, GetPlayerInterior(id)); below TogglePlayerSpectating(playerid, true);
