AFAIK the issue is that goto is now done client side, so you can have that
fancy line telling you the path and so on. The problem, of course, is that
the client does not necessarily know the full map at all times. Only the
server does. So you get this, hm, interesting behaviour.

Possible fixes:
a) kludge the client goto to do a unit move on one-step gotos.
b) queue a linear goto across unknown territory anyway. so it may not be
the optimal path, who cares. if the unit can't walk inside the requested
path the goto will abort anyway. if you really are being picky about this,
show the non-optimal path using a different line colour.

I guess b) is more interesting.
