Eniten ihmetyttää minua luvun XII "Ankkapalatsin erakko" tarinan seikka. Tarinassahan eletään vuotta 1947, no niin...edellisen luvun XI "Maailman rikkain ankka" lopussa eletään taas vuotta 1930. Siinä tarinassa, kolmanneksi viimeisellä sivulla, näemme Akun ja Dellan noin 5-vuotiaina. Sitten luvussa XII, seitsemäntoista vuoden kuluttua, näemmä normaalin ikäisen Akun ja myös normaalin ikäiset pojat(10-12v.?).
Kuinka pojat voivat olla ainakin 10-vuotiaita, jos 17 vuotta sitten hiedän äitinsä oli vasta 5-vuotias? 
Don Rosa, DCML, 28.6.1994:
Yes, I failed to answer your question about how could DD be
older in 1930 than HD&L are in 1947. I knew this was going against my
previous ideas on that subject when I wrote that chapter 12, but didn't
worry about it too much since those birth years in my notes have never
actually been printed anywhere. All I knew was I loved the scene of a
young DD kicking U$ in the fanny. However, it had to be a very young DD
in order for the act to seem more mischievous than mean. You'll agree
that if HD&L kicked U$'s butt it would seem very nasty since they are
about 10 or 12 or so. So I was thinking my 1930 DD was about 7 or 8. I
never tried to mentally readjust my Duck birth dates... let's see: say
DD and his sister were born in 1923. Then let's say HD&L were born in
1938? No, that would mean Della was only 15 when she had them. And
chapter 12 can take place no later than 1930 since it's after the stock
merket crash. Hey... whatcha know... I've screwed myself, eh? Any
suggestions? I think my only solution is to eliminate the comment that
DD was "even younger" than HDL when he last saw U$.1
