Clicking an anchor of a path selected whole (or one of several selected
anchors) with the Direct Selection tool left the selection as it was,
so the clicked anchor never became the selected one and Live Corners
and the anchor controls kept acting on every corner. A plain click now
selects that anchor alone, as the public documentation describes (a
click selects the anchor point, Shift-click adds others):

The press keeps the selection so a drag still moves every selected
anchor with the one held; only the release without a drag narrows it.
Shift still toggles, Alt still picks the whole path, and an anchor that
wasn't selected is still selected on the press.
