Comment (by eriktorbjorn):

 I haven't managed to reproduce this in the original interpreter - not yet,
 at least - and I don't understand what happens. I added some debug
 messages to Actor_v3::actorWalkStep() for what I think is the Rusty's
 ghost actor, and saw this:

 {{{
 Before: pos: 234, 66
 After: pos: 234, 66
 Before: pos: 234, -2303
 After: pos: 234, -2303
 Before: pos: 234, -4672
 After: pos: 234, -4672
 Before: pos: 234, -7041
 After: pos: 234, -7041
 }}}

 So at some point, but probably not inside actorWalkStep(), Rusty's Y
 coordinate got all screwed up, and he just keeps moving further and
 further away.
