...If that's not what that means, then what does that mean? Oh wow, good catch. It seems like there may have been a miscommunication on the backend here concerning this detail. I'll get this clarified with - it's possible I misunderstood what the intention was when I implemented this part, and if that's the case I'll get it cleared up and modified if necessary. I'll keep you updated!

We've cleared this up on our end, and Buddy GAs can now be gifted to people who already have GAs, and will stack in that case. I'll be posting this in the news later for visibility. Thanks again for catching that :)
