Which card did behave improperly ?
Aeon Chronicler

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/08/07: Eldritch Moon, duel

What exactly should be the correct behavior/interaction ?
no dump

Are any other cards possibly affected by this bug ?
-

It's because it calls in_play() before checking event - which I very carefully made it not do the last time I changed it. This is normally just a poor practice and performance sink (not to mention wrong for this card, and most like it - the power/toughness setting ability works in all zones), but it crashes cards with characteristic-defining abilities for power or toughness (i.e. */*, */whatever, or whatever/*) because the card parameter will be -1. Running git blame to find the change that resulted in the weird-looking check would have turned up commit 9a50dd55, which has a very thorough explanation why it'd be a bad idea to just remove it.

There shouldn't be any difference between adding a card to your hand with the debug menu or with Death Wish anymore, by the way, except that Death Wish is more clicks and costs you life.

Tempting as it is to just leave this, reverted back to the working version in d324a51.
