[rules-users] Rules not properly re-evaluating in 5.5

[CyBurr]

If am using a Stateful knowledge session with a rule flow group.  I am
inserting into working memory one instance of each class/type listed below.   
All of the rules fire except for rule 14.  Rule 14 and 15 are very similar
but for some reason only rule 15 fires.  If I swap the physical order of 14
and 15 in the DRL file then rule 14 fires and 15 does NOT.  If I change the
order of the LHS conditions for rules 14 and 15 then both rules fire.  I am
assuming the order of the LHS conditions or physical order of the rules is
irrelevant.  Is that the case?  If so, then can someone tell me what I’m
doing wrong?
