Upon delivery of Bagged Hatches to the Animal Relocator, they automatically get buried into a closest natural tile direcly underneath the Relocator. If there are artificial tiles under the Relocator the Hatch will "teleport" to the closest natural tile underneath, no matter how far away.
Steps to Reproduce
Deliver Hatches to the Animal Relocator and they will appear in the closest natural tile directly underneath, no matter how far away.
