Hello,

I am facing an issue when trying to calculate the private key at the collision of two checkpoint types. Specifically, I am working with the following pair:

Code:
82B0FB9D086D11223F7FD179 69267708D563F46CEEFFFFFFFFFFFFFFFFFFFFFFFFFF TYPE:0
82B0FB9D086D11223F7FD179 EE651EB9551FDBC41800000000000000000000000000 TYPE:2

For other combinations of types, I am able to successfully recover the private key. However, with this particular pair (TYPE:0 and TYPE:2), I am unable to find or compute the private key correctly.

Could anyone point out where I might be making a mistake? Are there any specific details or differences in the calculation logic when a collision involves TYPE:0 and TYPE:2 checkpoints? Any advice or suggestions on how to troubleshoot this would be greatly appreciated.

Thank you.
