[Cell_]

So you are resetting the player variables:

pawn Code:

static const empty_player[E_PLAYERS];
Player[playerid] = empty_player;

then setting the player's health to the reset variable under OnPlayerRegister:

pawn Code:

SetPlayerHealth(playerid, Player[playerid][Health]);
    SetPlayerArmour(playerid, Player[playerid][Armor]);

I hope the empty_player variable has health and armor set to 100.0?
