2nd Mortgage charge-off & ch 13 bankruptcy

We filed chapter 13 in March 2008. We were paying on our 1st and 2nd outside of the plan. However, when our home value dropped we met with our attny to see if we could get rid of the 2nd mort (value @ $30K). Our attny told us to stop paying the 2nd and save that $$ for attny fees to see what we could do with the 2nd by going back to court. Well several months passed and we could not get the $$ saved and we had stopped making payments on our 2nd (but have always pd our 1st-value @ $220K). We started making our 2nd mort payments again about 4 mos ago-because we were scared something might happen to our house. I recently pulled our credit report and it shows our 2nd as charged-off. What does this mean to our house and bankruptcy situation? Our ch. 13 will not be discharged until 2/2013.
