Doc - That's wrong. There's a parent company, anything associated with it is still liable.
WTBTSofPA was requested dismissed as a defendant from the Contri lawsuit and it was granted. IDK the exact details. Maybe a Legal Beagle here will recall and respond. But my recollection is the PA Corp is the "parent company" or at least the original Corp.
Further, I sued a developer who was building projects in multiple Corp names. XYZ#1; XYZ#2; all the way to XYZ#6. I worked for #4 and that corp defaulted several suppliers & contractors. Mr. XYZ (a multi millionaire) agreed to give these suppliers (including Doc & Assoc Inc) an IOU from XYZ#4 until it solved it's issues and could pay. XYZ#4 paid interest on time every month for 1 year and then stopped. In that period of 1 year, XYZ#4 liquidated all assets and work continued on the site by XYZ#5. Wanna guess what my IOU was worth? Do you think I could just go after XYZ#5? Or, XYZ#1? Or, even Mr Z? No to all. Every Corp is a single entity. If Corp #5 was not liable, I could not sue it for damages. Since XYZ#4 was broke, I could continue the suit (and pay my lawyer $250/hr to do that) and likely I would get a judgement, but since XYZ#4 was broke I wouldn't collect a dime.
(For further examples of this, examine Donald Trumps record on filing bankruptcy in multiple corporations.)
I'm not a lawyer, but I have paid the college tuition for pne of my lawyer's kids.
