In tests, some key managers occasionally register later than expected. This occurs because the VRFProve transaction check increments the nonce in the cache but fails as the node cannot be found in the registry. Subsequently, the RegisterNode transaction also fails due to an invalid nonce, as VRFProve transaction did not incremented the nonce in the consensus. Although the nonce is reset afterwards, this dance can persist indefinitely.
An alternative would be to somehow distinguish check-only failures from normal failures.
The impact of these changes on performance has not been tested.
