After receiving the wrong "blockfound_"
(block_height == 0)

"ledger.db" is broken

Thanks, never seen this issue before, what version are you running?
Do you have a log entry for that, please? And a copy of your blockchain if possible
I would love to know if you received it from my node, but it must be since there are no other nodes
I am still patiently waiting for someone to do the rollback hack before I fix it

from My TestCode
