Collectible Card Game Headquarters

Describe the Bug:

When Riftwing Cloudskate unsuspends, the game crashes, at least in the attached save.

Which card did behave improperly ?

Riftwing Cloudskate

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Born of the Gods v. 2, Sealed.

What exactly should be the correct behavior/interaction ?

Riftwing Cloudskate shouldn't crash the game, and should instead let you return a target creature to its owner's hand when it unsuspends.

Are any other cards possibly affected by this bug ?

Possibly other suspend creatures with enters-play triggers.

Same for Benalish Commander so there may be other suspend cards with the same bug.

With the recent overhauling of the "play_spell_for_free" and friends, this bug is fixed.
