A 60 point drop is very significant and something that is usually only achieved by the introduction of a negative item. I suppose it could be achieved as well in going from 1% aggregate utilization to maxed-out utilization on some profiles, but certainly you would know if you did this 
I would look closely at your reports and see what changed between last month and this month. Something negative was definitely added. Maybe a past negative item that fell off was re-reported or somehow resurfaced. Is it possible that one of your current accounts may have reported you late?
Slightly off topic here, but the 40 point drop you received from paying off your mortgage is very typical when the mortgage is your only installment loan. Once all current loans are closed out, FICO takes away the "credit mix" points that you previously had for having a current open installment loan that's almost paid off.
Sometimes losing a bad account drops your AAoA.
Where are you getting your scores from? If it's from creditkarma, you can disregard the scores, they are FAKO.

I have 3 derogs TL's (Charge Offs) all within 6 months of aging off. Aggregate balance approx $100K; I have two new positive TL's - a Secured credit card with a $200 line and 0% utilization and an auto loan that is on auto-pay so delinquency on either is not a factor. No credit use in between the crash 7 years ago and teh re-start 7 months ago.
In December 2016 one Charge Off aged off my credit file. The following month I lost 60 points.
Can anyone explain to me what happened? It seems whenever something that SHOULD improve my credit score happens, I lose points. When I paid off my mortgage in April 2016 I lost 40 points. At this rate in July I will have a credit file that shows 1 unused credit card with a low limit, 3 paid satis car loans, a paid satis mortgage, no derogatives and a score in the solid 400's. No mortgage, no debt, plenty of income, a 6-figure bank balance and I can't get credit to buy a pack of gum.
Hi Steve,
Credit Karma, Capital One, Credit Sesame and Trans Union all give you your Vantage score. Few, if any, lenders use this scoring model. FICO uses the Average Age of Accounts as one of its scoring parameters. It includes both open and closed accounts.
The Vantage model uses Average Age of Open Accounts and also gives it way too much weight. The Vantage model isn't factoring in the ages of your paid mortgage or auto loans.
Six months from now, when those 3 derogs are gone and your secured card and car loan have some more age on them, you'll get a nice score bump.
BTW, you need 2 more revolving accounts. Best scores are attained when you have at least 3.
