  I believe the problem is that obsoletion (and thus upgrade) effects don't
occur until the full chain of advances from one unit to another is researched.
In this case, Phalanxes (and Warriors) are obsoleted by Pikemen, which are
obsoleted by Musketeers; because (I assume) you haven't researched Feudalism,
you don't have Pikemen and thus your Phalanxes are not obsolete.  Weird but
true.
  It would seem more logical for obsolescence to be "transitive" (if A is
obsoleted by B and B is obsoleted by C, A is obsoleted by C), but maybe this
is a subtle way of punishing people who don't research the full technology
tree :)
