Edit: Ignore me. I edited the wrong script even though I knew which one was the right one O.o It works now.

I have the same problem, when I try to claim an adoptable with a promo code, the adoptable is inserted in the DB, but the owner field is empty.

Oh my goodness, looks like you have a big problem here. I have to work on the design project at this moment, so I will not be able to take care of this for tonight. The promocode system at this moment is set up in a way to handle user-specific codes only though. For now just try not to worry about public promocodes, I will look into ways to fix it later.

It worked for me.... just do what HoF told me to do.

Oh so it worked? Thats nice, I am not sure if I should consider this a glitch yet, but I will make sure to improve the promocode system further in Mys v1.3.2 so it can handle not only user-specific codes, but also public and multiple-user(more than one user, but not everyone).

It's not a glitch... but people will think they're able to enable all users to use it.
