Summary:
When /locate mansion is entered in the chat, the world freezes for a few seconds every time. In worlds with the Caves and Cliffs toggle enabled, the freeze lasts longer. All other structures do not freeze the world when located with the /locate command.

Steps to Reproduce:

1. Create a new Infinite world with cheats enabled
2. Enter /locate mansion in the chat

Observed Results:
The world freezes. After a few seconds, the world unfreezes and the command returns coordinates to the woodland mansion.

Expected Results:
/locate mansion should not cause worlds to freeze.
