Bizarre Monster Book Error

Well your proof is wrong and just a coincidence.

I was training at Skele's today and as evidenced by my previous posts in the post your monster book thread, I had all of the skele cards. A skele card dropped, I picked it up, and it registered as a card I don't have and gave me the exp buff. So I guess those two incidents you've run into were just bad luck.

I'm confused. What are you trying to say? My point was I believe it's more than simply a display error. If it was just a display error, no matter what numbers your cards change to, the game remembers what you have and won't affect what cards you can and can't get (like picking up a Pap card if you already had 5).

With your post, you're arguing my view is incorrect (which means you're saying the book is working as intended, just showing wrong numbers). However, you're doing so by providing an example that proves my point. Am I misunderstanding? You had 5 of each Skele/Skelo card, so you shouldn't ever be able to get another if this was only a display error. You said you were able to.
