1- Takklemaggot is not an aura,doesn't attach to creature.
2- More important it never triggers in upkeep to have an effect on enchanted creature.
Which card did behave improperly ?
Takklemaggot

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Jan 01, 2014 : Commanding the revision of Ice Age v2 - DUEL

What exactly should be the correct behavior/interaction ?
1- Takklemaggot
2- Takklemaggot triggers on enchanted creatures upkeep and puts a 0/-1 counter on that creature.

Are any other cards possibly affected by this bug ?
-

As of BotGv1, Takklemaggot correctly put counter on creature until death but then a legacy card is created and nothing else happen, no other target to choose nor damage to player.

All fixed in b870b2f
There's still a little bug : Takklemaggot won't lose the "Aura" type if is not enchanting a creature, but oh well...
