Issue solved thanks to a guy on the sa-mp discord. If anyone else has this issue, put this at the top of the code:

PHP Code:

my_SetPlayerArmour(playerid, Float:amount)
{
    if(amount < 0.0)
    {
        amount = 0.0;
    }

    return SetPlayerArmour(playerid, amount);
}

#if defined _ALS_SetPlayerArmour
    #undef SetPlayerArmour
#else
    #define _ALS_SetPlayerArmour
#endif
#define SetPlayerArmour my_SetPlayerArmour
