[BLOCKING LIVE CONTENT] Pathfinding issues in A Pirate's Christmas

Windows_Minecraft - Release_891562
(RC 1.4.0.1)

Summary:
The fiddle (llama) no longer pathfinds to the pirate in the volcano in "A Pirate's Christmas". This worked correctly in the last live build. When the llama floats to the top at the completion of the snow melting, it should pursue the pirate on the other side of the cave. The completion of this mini-game requires this to work. If you manually bring the llama closer, it accurately pathfinds. Contact Quinn or Greg who have access to a world snapshotted in place in the Noxcrew slack channel. I can't tell if this is broken due to proximity or water, but it will work properly if you bring the fiddle closer to the pirate.

Impact:
This map no longer works.

Repro Steps:
1. Get the world from the Noxcrew slack channel and open it
2. Look at the fiddle in the top of the ice formation to the left. Look at the pirate to the right. Notice how the llama is not pursuing the pirate
3. /tp @e[type=llama] @s If you're standing where the world should have loaded you, the llama will now pursue the pirate properly.

Observed Results:
The fiddle does not pursue the pirate from out of the top of the ice formation.

Expected Results:
The fiddle should pursue the pirate from out of the top of the ice formation.
