Any way to recover ether sent from proxy to CPO contract after self-destruct ? 

I have called self-destruct on a proxy contract. It sends all remaining ether balance to CPO and now I am having trouble retrieving it from CPO.

That is my mistake... as I should either extend the CPO with a withdraw function or withdraw all ether from proxy before calling self-destruct


Anything I can do to recover the ether sent to CPO at this point ?
