You can claim unlimited number of <adoptable> with conditions that tell it otherwise.

No matter the condition you set when creating animal, you can buy or obtain it infinite times.

Like past versions of this script, I have been unable to get an adoptable that I want to be limited edition and seasonal. Promo codes can be used by a member more than one time and adopts conditions such as below will do nothing it is supposed to. Short story, it's very buggy.

For example here is what is checked:

Was this ever corrected?

I am trying to restrict how many times someone can adopt from the adopt page -- one to a customer -- and it doesnt work, I've checked everything and filled it all in right.
