*There is absolutely nothing in Schroedinger's equation that says the
amplitude of the universal quantum wave collapses to exactly 1 and is
zero everywhere else when a measurement is made, there isn't even
anything in it that explains what a "measurement" is. The rule you
mention was added on by the Copenhagen people, so according to them
there are two separate rules of physics, one set of the laws of
physics is for things that are not being observed, and the other set
of the laws of physics are for things that are being observed. Many
Worlds advocates say there is only one set of the laws of physics.

And apparently that there is no such thing as a measurement leaving a
system in an eigenstate of an observable. This is will come as a
surprise to many experimentalist.
