Time Capsule?

[Attribule]

So a while ago my villager asked me to bury her time capsule for her and handed it over to me. However, it isn't in my inventory.

Is this a bug? Or does the capsule just bury itself and pop up when it's convenient; i.e. she asks for it back?

The time capsule will be in your "Letters" inventory, not your normal inventory.

Thanks!
