From "emacs -Q"?  If so, please show a complete recipe, because I
cannot reproduce this.  (Of course, you can only have the last line at
the bottom of the window once you have enough stuff in the buffer to
fill the window, but I assume you have accounted for that.)

Again, is that in "emacs -Q"?  If not, please try "emacs -Q".  Here's
what I did:

  emacs -Q
  M-: (setq erc-modules '(scrolltobottom)) RET
  M-x erc RET RET RET RET RET

Then I wait for enough stuff to arrive that Emacs recenters, and hit
RET one more time.  At this point, the last line is scrolled to the
bottom of the window.
