I just found this one. I can send a gift to a pirate, then delete them, then add them, then send a gift to them again. Not sure if this same bug allows other operations to repeat or not (like assisting with adventures, challenges, etc)
That should not have an impact on sending to the same user within 24-hrs. Are you sure you were able to send to the same user in the same 24-hr period?
Yes, same user and the time difference was under one hour. I sent a gift to the user, then we deleted, then we added and I sent another gift.
