How to get transaction with Bitcoin Core? I've have a fully tx index node in v.11 and I can do the following below just fine, 

bitcoin-cli getrawtransaction c6556ca7e143d108f5ef594057ff83a78bceb4b5fdc565ae160b4783cddad00f

but with a fully tx index node in v.12, I cannot and I get an error 

error code: -5
error message:
No information available about transaction


So what has change in v.12 that broke this and what can do to get this functionality back. I already have txindex=1 in my conf file and I already tried bitcoind -daemon -reindex
Can you right now put txindex=1 in your bitcoin.conf on both, and restart your node? That will cause a failure if the database was not created with txindex. If it continues, and there are still transactions that can't be found by getrawtransaction, file a bug report on https://github.com/bitcoin/bitcoin/issues.
