AI "failed to target" when casting Torrent of Souls

**Describe the bug**
In a duel at a Shandalar "Skull Cave" location (probably [skullcave_3.tmx](https://github.com/Card-Forge/forge/blob/a2b324c9ce12bc3a3ca54fbaf11c42439a3f94eb/forge-gui/res/adventure/common/maps/map/skullcave/skullcave_3.tmx)), an AI "Abyssal Baron" player tapped all its lands for no effect. The log menu said:

> [Torrent of Souls](https://scryfall.com/card/mm3/213/torrent-of-souls) - Couldn't add to stack, failed to target - Return up to one target creature card from your graveyard to the battlefield if {B} was spent to cast this spell. Creatures target player controls get +2/+0 and gain haste until end of turn if {R} was spent to cast this spell. (Do both if {B}{R} was spent.)

An [Eater of Hope](https://scryfall.com/card/mic/115/eater-of-hope) creature was in its graveyard. A swamp & mountains were tapped. There was a viable target creature and player (also the spell said "up to one target creature"), so the spell should have succeeded. The log didn't say WHICH target was at fault.

According to [enemies.json](https://github.com/Card-Forge/forge/blob/a2b324c9ce12bc3a3ca54fbaf11c42439a3f94eb/forge-gui/res/adventure/common/world/enemies.json#L6), the deck was [demon_swamp.dck](https://github.com/Card-Forge/forge/blob/a2b324c9ce12bc3a3ca54fbaf11c42439a3f94eb/forge-gui/res/adventure/common/decks/standard/demon_swamp.dck).
