Player can get out of bounds near the waterfall in Honeycomb Fields

The player can get outside the intended playable area near the waterfall by jumping/climbing onto the surrounding terrain. From there, the player can walk on top of the cliffs and access areas that appear to be outside the normal map boundaries

Steps to reproduce:

1. Go to the waterfall area shown in the attached video

2. Move to the rocks/ledge next to the waterfall

3. Jump onto the terrain beside the waterfall

4. Continue jumping/climbing upward

5. The player can reach the top of the cliffs and move outside the intended playable area

Expected result:
The player should be prevented from climbing or jumping outside the playable map boundaries

Actual result:
The player can climb onto the terrain outside the normal playable area and freely move around above/outside the map
