PUTTZOO: Animation overlap bug with final iceberg

[Thunderforge]

During the puzzle to free the baby hippo, moving the final iceberg (the square one) results in an animation bug.

The iceberg moves past three penguins standing on ice. It correctly moves underneath the first penguin and his section of ice, but over the second penguin and his ice, before moving under the third penguin. After a moment, the ice then jumps underneath the second penguin and his ice. Instead, it should move underneath all three.

See the attached animated gif for a demonstration.

Reproduction

1. Load the attached savegame
