Ok so I followed all the steps and got the regenrating currency recipee working.
I was now testing the referral codes recipe but it is not working .
I followed all the steps then , when i press redeem code. It always gives out in console,
SUCCESS!... You Just Recieved:
after that there is nothing and nothing is added in inventory of the player.
Even though If I have not entered any code and just pressed redeem still it shows the same output.
