This fixes the various edge cases that occur when multiple Captures or Capturable traits are defined on an actor and are toggled using conditions. The Sabotage threshold field moves from Capturable to Captures in order to simplify the plumbing. The previous behaviour ingame can be restored by creating a new capturable type for each threshold level, each with their own Captures trait.
