Vulnerability details Impact Detailed description of the impact of this finding. _buyoutLien() in LienToken.sol failes to update the new PublicVault's slope, yIntercept, and s.epochData[...].liensOpenForEpoch.

Proof of Concept Provide direct links to all referenced code in GitHub. Add screenshots, logs, or any other relevant proof that illustrates the concept. Suppose a PublicVault P calls _buyoutLien() to replace an old lien A by a new lien A`. The slope, yIntercept and s.epochData[...].liensOpenForEpoch for A's payee have been modified as follows, but the function fails to update these parameters for P, the payee of A'.
