> When removing rules from knowledge which have logically inserted (justified) objects, only one object (from first removed rule) will be retracted. 
> In example from AddRemoveRule#184: as it removes the first rule, it re-initializes all other path memories and, in particular, marks them as unlinked (AbstractTerminalNode#204)
> Later, when it tries to flush the deletions (AddRemoveRule#280), the unlinked status prevents the propagation from taking place.
