Piggy Bank offers can only use stackable items, not bundles

When configuring a Piggy Bank offer, the reward item must be a regular stackable item that supports quantity. Bundles are not supported as the Piggy Bank contents.

What this means in practice

• The offer card will not display bundle contents as Piggy Bank contents.
• If you need a currency-style Piggy Bank reward, configure it as a stackable item instead of a bundle.
• Set the Piggy Bank reward using the target item and the appropriate Tier Value for each tier.

Example

Instead of using a bundle, configure a stackable item such as item_starmoney_0 and set Piggy Bank tiers with values like 5600 and 11200.

Summary

Use Piggy Bank only with a normal quantity-based item. If the intended reward is currently modeled as a bundle, convert the setup to a stackable item for the Piggy Bank campaign.
