How does a Chapter 13 case closing without discharge affect me?

Something doesn't seem right about your post so you should really consult with a local bankruptcy attorney.  Many bankruptcy attorneys offer free or reduced rate consultations.  Or, if you hired an attorney for your Ch13 case, you should ask them the significance of any language used at a hearing.  The entire goal of a bankruptcy case is to get a discharge, even in a Chapter 13 case as debtors often don't pay their debts in full.  If you didn't in fact get a disccharge, then you are still liable to pay any remaining amounts on those debts.  The significance of any previously filed cases should have been discussed earlier by the Trustee and the Judge.  This aspect of your post seems strange.  Closing your case as satisfied without a discharge sounds very odd.
