[ERROR] invalid orm id

[MtPlayerZ]

It is my first time using the plugin and I am getting a flood of errors in the "mysql.log" file.
Most errors are: "orm_destroy: invalid orm id (number)" and "orm_update: invalid orm id (number)".

In the places where I used "orm_destroy" I did the following check:
if (PlayerInfo [playerid] [OrmID]! = MYSQL_INVALID_ORM) orm_destroy (PlayerInfo [playerid] [OrmID]);

but I still get errors in this function.

Would you be able to tell me if it could be a fault when I program or if it is with the plugin, vps or something?

ps: sorry for the bad english, i'm using the translator.
