Reproduction steps: 1. Deploy a few relics. 2. Overgrowth and haunt them. 3. Destroy them. 4. After 5 turns the spells will summon saplings and shades even though the relics don't exist anymore. So I'm reporting this as a bug because it's unclear. The description says "After the effect ends", which either means that killing a relic early should spawn the summons or - for consistency's sake - they shouldn't spawn at all if a relic dies beforehand. @Sokolov What's the consensus on this one?
