Unnecessary faces in certain hanging propagule models

The bug

Hanging mangrove propagules with an age above 0 have two unneeded faces: the top of the brown cuboid, and the bottom of the greenish cuboid.

How to reproduce

1. Find a hanging mangrove propagule of sufficient age
2. Enter Spectator mode
3. Fly inside

Expected results

As these faces inside of the plant cannot be observed in normal gameplay, the model file would skip these faces as to decrease model file sizes and the effort needed for rendering these faces.

Actual results

These faces exist.

How to fix

Removing these faces from the model files would resolve this issue entirely. A pack to fix this is forthcoming.
