Spells/Traps that would leave the field at the end of the chain should remain on the field until after "immediately after this effect resolves" effects resolve.

[VforViolin]

Currently, when a card/effect with "Immediately after this effect resolves" in it's text is activated as chain link 1, such as Woes of the White Forest (62995268), the card will leave the field after the chain resolves and materials are selected to perform the summon, but before the summon actually occurs.

What should happen is any spell/traps with an "Immediately after this effect resolves", effect that are activated as chain link 1, that would leave the field upon resolution of the chain, should remain on the field until after the "Immediately after this effect resolves" effect finishes resolving.
