Conquests of the Longbow - Tower arcade sequence impossible

[CaptainJei]

When I get to the sequence near the end of Conquest of the Longbow where you have to climb down the tower while a monk is throwing rocks at you, the monk only throws one rock, and then freezes, leaving the sequence unable to progress. Often the rock falls in the wrong direction on the screen, and either way, it does not splash into the water.

ScummVM version 1.3.1
I installed the official patch from the Sierra help pages. There was no warning message about the Green Man loop when I started the game.

It works just find in the newest daily build (as of this posting). Apologies for posting before trying the daily build first.
