Description

Currently, an NPC riding a controllable NPC boat can pathfind very nicely, but only through 1-block-deep water.

If it tries to pathfind to a location in deeper water, it instantly fails. If it tries to pathfind to a location in 1-block-deep water but it itself is in deeper water, it just sort of spins in circles.

Ideally the behavior that is seen in 1-block-deep water would be seen in deeper water too.
