There was money on the fourth day of the 12 Days of the Spiral event that each pirate received, if we chose to do so. I thought that I was very lucky when I got 10000 gold, yet, I never actually received the gold. After I accepted the gift, I ended up with the same amount of gold as before.

I think that I might have been at too much gold, so if this gold was entered into my current gold, it'd be over the limit. I wouldn't worry about it actually, especially considering it might not actually be valid.
