[fixed]Ivory Gargoyle returns immediately not at next eot

[Aswan jaguar]

Describe the Bug:
1- Ivory Gargoyle returns immediately to battlefield when destroyed not at next eot.
2- If Ivory Gargoyle is copied by Kiki-Jiki, Mirror Breaker and that token is destroyed doesn't make you skip your next draw step.(No legacy card of the effect is created). this seems not rules wise effect is one.

Which card did behave improperly?
Ivory Gargoyle

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 778ccb5 version - duel

What exactly should be the correct behavior/interaction?
1- When Ivory Gargoyle dies, return it to the battlefield under its owner's control at the beginning of the next end step.
2- Token copies of Ivory Gargoyle behave the same way the original card does. That means that when one of those tokens dies, its controller skips his/her next untap step, which is indicated by a legacy effect card appearing on the battlefield. this seems not rules wise effect is one.
Are any other cards possibly affected by this bug?
Molten Firebird the timeshifted version of Ivory Gargoyle they don't share code but are bugged the same for 1st bug. I didn't check for 2nd.

In addition to what AJ and Wally have reported: I noticed that when this instant-return Ivory Gargoyle dies multiple times in a turn it builds up several skip-next-draw effect cards. But all seem to get cleared by a single skip of the draw on Ivory Gargoyle controller's next turn.
