Explorer possibly fixed due to unsafe densities

  It was found that Explorer could enter a broken state as it were when
induced to a unsafe density.

  It's order of operations was:
  1. Change state
  2. Call next() to move to ??? (target would be set first, which may
have been the problem)
  3. Target get's set to non-zero indicating it should be used rather
than deducting from density scans

  As stated above, it is beleived that the issue was that target was
being set after code which depended on it's value.
