Panic when syncing `wallet` #2

Closed rustaceanrob closed 3 months ago

rustaceanrob commented 5 months ago

Two subsequent runs of cargo run --example wallet results in the second call panicking with message: Error: introduced chain cannot connect with the original chain, try include height 200582 error: process didn't exit successfully:target\debug\examples\wallet.exe(exit code: 1). Seems like an error case on the LocalChain wasn't handled?

This could be caused by the error case "two disjoint chains cannot merge" if the local and remote tip differ but the block at height tip-1 is the same. 

       B
---A <
       B'

That's odd. I can try to reproduce by syncing to the same height with same hash as the last sync. In which case B = B' and something else weird is happening.
