When the Happy Ghast faces south, the boats align in the same direction.
When the Happy Ghast faces other directions, the boats always point in one fixed direction, causing the ropes to twist and tangle together.
Steps:
First, place a Happy Ghast.
Restrain the Happy Ghast to prevent it from moving (this issue does not occur when idle).
Use a lead to tie the boat to the Happy Ghast.
Use a Happy Ghast favorite item (snowball, play session—"when not equipped").
First, make it face south—the boat's direction will be correct.
When the Happy Ghast faces east or west, the boat remains fixed in one direction.
After facing north, a severe error occurs: the lead twists and tangles together, and even pushing the boat away with the body doesn't help.
Note: This issue does not occur when the player is riding the Happy Ghast or standing on its head.
