The problem is when reorganization occurs on chain, so the parent block does not exist any more. function
handleReconcileImpl()should check if the obtained block isnil(parent == nil):parent, err := t.provider.GetBlockByHash(block.ParentHash, false)There are some additional places in
blocktracker.goand tracker.go which should be handled also. They are introduces in this PR as well.
