Collectible Card Game Headquarters

Describe the Bug:
1- Knowledge Vault: exiled card is not in exile zone - vanishes.fixed
2- Knowledge Vault: The exiled cards are not shown as empty legacies (simulate face down)attached to Knowledge Vault so we know how many cards we have exiled with it.
3- Knowledge Vault: can the exiled cards be shown as face down in exile?
Which card did behave improperly?
Knowledge Vault

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink 2016/08/27: Eldritch Moon v2, duel

What exactly should be the correct behavior/interaction?
1- Knowledge Vault: exiled card is in exile zone.
2- Knowledge Vault: The exiled cards are shown as empty legacies or better have only a legacy that recalculates how many cards are exiled with it (without name in title to simulate face down) attached to Knowledge Vault so we know how many cards we have exiled with.
3- Knowledge Vault: Exiled cards are shown as face down in exile.

Are any other cards possibly affected by this bug?
For the face down not shown as face down many.

Fixed that cards are not in exile zone in commit 484c9797. For the rest Korath says more about how he solved this issue in shandalar here:
