Although this is an unlikely scenario, Wanda will refuse to be revived by another player if her inventory is full of her watches, since she holds onto them after death.
1. Spawn a Wanda or have another player play as her.
2. Fill every slot in Wanda's inventory with any of her watches.
3. Have Wanda die by any means.
4. Attempt to revive her using a telltale heart.
