Collectible Card Game Headquarters

Describe the Bug:
When choosing to return Undead Gladiator from graveyard to hand during upkeep, the game doesn't ask for a card to discard. It's returned to hand as intended, though.

Which card did behave improperly ?
Undead Gladiator

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
BotG, Duel

What exactly should be the correct behavior/interaction ?
When choosing to return Undead Gladiator from graveyard to hand during upkeep, the game asks for a card to discard.

Are any other cards possibly affected by this bug ?

That's strange, the code seems fine, could please re-check on a clean game ?

The savegame I posted was from a clean game I created after I first noticed the bug in a game using a 'real' deck. Anyways, I was able to reproduce the bug some moments ago.

At a glance, it looks like it only discards when the AI is activating via EVENT_GRAVEYARD_ABILITY_UPKEEP, not when a human is via EVENT_PAY_FLASHBACK_COSTS.
