The Mangrove Propagule cross model is stretched, but not double-sided. This applies to the ground model, the cross part of the hanging model, and even the flower pot model.

Interestingly, despite other cross models looking incorrect from the east and west sides, the mangrove propagule mirroring is actually incorrect on the north and south sides. This may mean the block model is rotated 90 degrees.

Expected Result

The Mangrove Propagule is double-sided like all other saplings.

Observed Result

The Mangrove Propagule is not double-sided, causing it to look incorrect from the north and south.
